Question

1. 2x-10 =-3x .solve the equation. 2. 5x+2=10+3x. 3. 2-3a+7=8a + 3-a .​

Answer 1

Answer:

1 . 2x -10 = -3x

3x + 2x = 10

5x = 10

x = 10/5

x = 2

2. 5x + 2 = 10 + 3x

5x -3x = 10 -2

2x = 8

x = 8/2

x = 4

3 . 2 - 3a + 7 = 8a + 3 - a

2 + 7 - 3 = 8a -a + 3a

6. = 10a

6/10= a

Answer 2

Answer:

1. 2x-10=(-3x)

-10= -5x

2=x

2. 5x+2=10+3x

5x-3x=10-2

2x=8

x=4

3. 2-3a+7=8a+ 3-a

2-3a+7=7a+3

-3a-7a=3-9

-10a= -6

a=3/5
