Answer:
9.6
Step-by-step explanation:
✯Hello✯
↪ so first we need to 'kill' the smaller x. This can be done by taking 2x from 7x
↪ That leaves us with 18= 5x-30. Add 30 on both sides and we get 48=5x
↪ we divide by 5 on both sides
↪ that gives us 9.6

Final answer:
To solve the equation 2x+18=7x-30, subtract 2x from both sides, add 30 to both sides, and divide both sides by 5 to find x = 9.
Explanation:
To solve the equation 2x+18=7x-30, we need to isolate the variable x on one side of the equation. First, we can start by simplifying both sides of the equation. Subtracting 2x from both sides gives us 18 = 5x - 30. Next, we can add 30 to both sides to get rid of the -30 on the right side. This gives us 48 = 5x. Finally, divide both sides by 5 to solve for x. The final solution is x = 9.

4x - y = 18
Add both the equations together.
3x + 4x + y - y = 17 + 18
7x = 35
x = 5
Plug in x = 5 into any equation, and solve for y.
3(5) + y = 17
15 + y = 17
y = 2
Your solution is (5,2).

Call the rung number
a. 5(x+4) + 2(x+3)
b. 3(y+6) + 4(y-5)
Answers
Answer:
Step-by-step explanation:
a. 5(x+4) + 2(x+3) = 5*x + 5*4 + 2*x + 2*3
= 5x + 20 + 2x + 6
= 5x + 2x + 20 +6 {bring like terms together}
= 7x + 26
b. 3(y+6) + 4(y-5) = 3*y + 3*6 + 4*y - 4*5
= 3y + 18 + 4y - 20
= 3y + 4y + 18 - 20 {bring like terms together}
= 7y - 2
