Answer:
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
