Question

All are Algebra 1 questions . What is x ?

1. -4x -7(-3x-6 ) = 195
2. 8(x+5) +4 = 60
3. 6+5(x - 7)) = 71
4.-6x+5(-2x-11)= 137
5.-3x-5(-3x-9) = -51

Answer 1

1.9

2.2

3.20

4.-12

5.-8

Explanation:

1. distribute number outside of parentheses

-7 times -3x and -7 times -6

now you have -4x +21x +42=195

2.combine like terms

17x+42=195

3. subtract/add the constant(number without variable)

17x=153

4.divide both sides by 17

x=9
