Question 250068
Substitute the "value" for y from the first equation into the second equation.
The second equation then becomes 3x+2(x+2)=9

ASp;ve the after using the DISTRIBUTIVE PROPERTY, the second equation becomes 3x+2x+4=9

Solve 3x+2x+4=9 for x

Subtract 4 from each side of the equation

The equation is now 3x+2x=5

Combine like terms so 5x=5

Divide each side of the equation by 5 so x = 1

To solve the system of equations for the other variable "y", replace "x" with 1 in he first equation, so y = 1 + 2 = 3.

So, x = 1 and y = 3.
