Answer:

Step-by-step explanation:

99x - 44y = -605

-99x + 63y = 738

19y = 133

y = 7

-9x + 28 = 55

-9x = 27

x = -3

(-3, 7)

Set 4x equal to x+30 and solve.

prisoha [69]

Answer:

x = 10

Step-by-step explanation:

1) Subtract x from both sides.

4x − x = 30

2) Simplify 4−x to 3x

3x = 30

3) Divide both sides by 3

x = $\frac{30}{3}$

4) Simplify $\frac{30}{3}$ to 10

x = 10
