Solve for x:
4x - 12 = 8x + 24
Answers
Answer: -9
Step-by-step explanation:
To solve the equation, isolate the variable, then use basic arithmetic.
Subtract 4x on both sides to obtain the equation:
-12 = 4x + 24
Subtract 24 on both sides to isolate 4x, and obtain the equation:
-36 = 4x
Finally, divide both sides by 4 to obtain the following:
-9 = x
Final answer:
To solve the equation 4x - 12 = 8x + 24, shift all terms with x to one side and constants to the other, then isolate the x. The solution of the given equation is x = -9.
Explanation:
The goal here is to find the value of x by solving the equation 4x - 12 = 8x + 24. This is a type of linear equation which can be rearranged to eventually isolate x on one side.
First, you want to bring all terms with x to one side of the equation and constants to the other. To do that, you can subtract 4x from both sides which will give: -12 = 4x + 24.
Then, subtracting 24 from both sides of the equation will give: -36 = 4x.
Finally, dividing by 4 on both sides will isolate x, so: x = -36 / 4 = -9. So, the solution of the equation is x = -9.

Answer:
Angles of △EFQ:
m<EFQ = 100°
m<EQF = 14°
m<FEQ = 66°
Step-by-step explanation:
ED is the diameter of the circle O
so m<EFD = 1/2 (180) = 90°
Given m∠DFQ = 10°
△EFQ
m<EFQ = m<EFD + m∠DFQ = 10° + 90° = 100°
arc EF = 28°,
so m<EQF = 1/2 (28) = 14°
m<FEQ = 180 - ( 100° + 14°) = 66°
Answer:
m<EFQ = 100°
m<EQF = 14°
m<FEQ = 66°

4x+11<23
4x<12
x<3
First, you subtract the 11 from both sides of the equation:
4x+11<23
-11<-11
4x<12
Next, divide both sides of the inequality by 4:
4x<12
4 < 4
x<3

Step-by-step explanation:,,
Answer:
The answer is B:subtract 1,add x,divide by 4
The other answer is D:add x,subtract 1,divide 4
Step-by-step explanation:
when you subtract 1 you isolate 3x so the equation looks like 3x=-x+3
the next step is to add x to both sides so you isolate the x to one side after doing that your equation should look like 4x=3,after this you divide both sides to the solution x=
The answer is also D because if you add x to both sides u isolate x to the left side so the equation will look like 1+4x=4 the next step will be to subtract one from each side and after doing this the equation should look like 4x=3 which should look familiar because its the same exact solution as B was so the answer to this choice is x=
With that evidence I can reasonably say that answer to the question is B,and D
