Solve the system using elimination. Explain
16x - 7y = 4
x-7y=-26

Step-by-step explanation:

16x - 7y = 4

-x + 7y = 26

15x = 30

x = 2

2 - 7y = -26

-7y = -28

y = 4

(2,4)

the line of

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
