Question

Does someone mind helping me with this problem? Thank you!

Answer 1

x = 5

y = 8

Explanation:

2x + y = 18

y = 4x - 12

First, let's find the value of x:

• Since y = 4x - 12, we can replace the y in the first equation with 4x - 12.

2x + 4x - 12 = 18

• Add like terms.

6x - 12 = 18

• Add 12 to both sides of the equation to isolate x.

6x = 30

• Divide both sides by 6.

x = 5

Now onto the value of y:

2x + y = 18

• We know x = 5 from the previous work so we can replace x with 6 in the equation.

2*5 + y = 18

• Multiply.

10 + y = 18

• Isolate y.

y = 8
