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

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

Step-by-step 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

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
