Question

Use subsitution to solve
6x + 4y = 14
y = 5

Answer 1

x = -1

Explanation:

replace y with 5

6x + 4*5 = 14

6x + 20 = 14

-20 -20 Subtract 20 from both sides of the equation

6x = -6 Divide by 6 on both sides of the equation

x = -1

Answer 2

Explanation:

1. 6x + 4(5) = 14

2. 6x + 20 = 14

3. move 20 over

4. 6x = 14 -20

5. 6x = -6

6. Divide

7. x = -1
