Question

Find the solution of the system of equation
-6x-2y=-40
-7x-2y=-44

Answer 1

Step-by-step explanation: Solve for the first variable in one of the equations, then substitute the result into the other equation.

Point Form:

(4,8)

Equation Form:

x=4,y=8 If this didn't help send me a message and we can work one on one.

Answer 2

See below!

Explanation:

Given equations:

-6x - 2y = -40 -------------------(1)

-7x - 2y = -44 --------------------(2)

• Subtract Eq. (2) from Eq. (1)

-6x - 2y - (-7x - 2y) = -40 - (-44)

-6x - 2y + 7x + 2y = -40 + 44

-6x + 7x = 4

x = 4

Put x = 4 in Eq. (1)

-6(4) - 2y = -40

-24 - 2y = -40

• Add 24 to both sides

-2y = -40 + 24

-2y = -16

• Divide both sides by -2

y = -16/-2

y = 8
