Question

-7x - 6у = 4
x = -3y + 8
Solve the system if equations
X=?
Y=?

Answer 1

(x, y) = ( -4 , 4)

Explanation:

STep 1: substitute the given value of x into the equation -7 x - 6y = 4 which will be -7 (-3 y + 8) - 6 y = 4

STEP 2: solve the equation for y so basically -7 (-3 y + 8) - 6 y will be y = 4

STEP 3:substitute the given value of x into the equation so y = 4 would be

x = -3 x 4 + 8

STEP 4: solve the equation for x. -3 x 4 + 8 which you'd end up with x = -4
