Then, you can use either cross multiplication or multiply the numerator and denominator by the same number to help solve for x. Personally, I prefer cross multiplication, so that's what I'll show you here:
Finally, solve for x:

The system of equations are solved using substitution method and there are infinite number of solutions
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
To solve the given system of equations using the substitution method, we can follow these steps:
Step 1:
Solve one of the equations for one variable in terms of the other variable.
Let's solve the first equation, y - 3x = 7, for y in terms of x:
y = 3x + 7
Step 2:
Substitute the expression for the solved variable into the other equation.
Substitute the expression for y from step 1, which is 3x + 7, into the second equation, 21 + 9x = 3y:
21 + 9x = 3(3x + 7)
Step 3:
Simplify and solve for the remaining variable.
Now we can simplify the equation and solve for x:
21 + 9x = 9x + 21
0 = 0
Hence , resulting equation is a true statement, 0 = 0, which means that the system of equations is dependent and there are an infinite number of solutions.

The answer is B
let me show my answer
-3x+y=7;9x+21=3y
Solve -3x+y=7 for y
Add 3x to both sides
-3x+y+3x=7+3x
y=3x+7
Substitute 3x+7 for y in 9x+21 =3y
9x+21=3y
9x+21=3(3x+7)
Simplify both sides of the equation
9x+21=9x+21
Add -9x to both sides
9x+21+-9x=9x+21+-9x
21=21
Add -21 to both sides
21+-21=21+-21
0=0
Answer : B , Infinitely many solutions

66 ÷ 78 = 0.85
Next, move the decimal point over two places.
0.85 = 85%
Shawn got 85% on the science test.
Hi there! ;) The answer to your question is 0.85 or 85%. I got the answer because I divided 66/78(66 divided by 78) which equals 0.845 but I rounded it because 5,6,7,8,9 means round up.
Hope I helped! :D
