Answer:

1.7x-2=8+2x

Step-by-step explanation:

collect like terms

7x-2x=8+2

5x=10

divide 5 both sides to get the value of x

5x/5=10/5

x=2

Answer:

1. x = 2

2. a = 2

4. a = 5.

Step-by-step explanation:

1. 7x - 2 = 8 + 2x

7x - 2x = 8 + 2

5x = 10

x = 2.

2.  4 ( 3a + 1 ) = 3a + 22

12a + 4 = 3a + 22

12a - 3a = 22 - 4

9a = 18

a = 2.

4. a - 3(2a) = -25

a - 6a = -25

-5a = -25

a = 5.

( I couldn't do number 3 because there is no variable in the equation).
