1)4-2(x + 19) = 50
2)7(x-3)-14=70

1. x=4

2. x=15

Step-by-step explanation:

1. Add '-42' to each side of the equation.

42 + -42 + -2x = 50 + -42

Combine like terms: 42 + -42 = 0

0 + -2x = 50 + -42

-2x = 50 + -42

Combine like terms: 50 + -42 = 8

-2x = 8

Divide each side by '-2'.

x = -4

Simplifying

x = -4

2.

Add '35' to each side of the equation.

-35 + 35 + 7x = 70 + 35

Combine like terms: -35 + 35 = 0

0 + 7x = 70 + 35

7x = 70 + 35

Combine like terms: 70 + 35 = 105

7x = 105

Divide each side by '7'.

x = 15

Simplifying

x = 15

pi x^2
