Question

A). x+4=10-x


B). -10+10x=4x+2

c). -15+15x=6x+3

D). -4a-20= -12a+12

Answer 1

A) X + 4 = 10- X

X+X=10-4

2X=6

X=6/2

X=3

B)-10+10X=4X+2

10X-4X=2+10

6X=12

X=12/6

X=2

Answer 2

a)  x+4=10-x

x+x = 10 - 4

2x = 6

x= 6/2

x= 3

b)  -10+10x=4x+2

10x - 4x = 2 + 10

6x = 12

x= 12/6

x= 2

c) -15+15x=6x+3

15x - 6x = 3 + 15

9x= 18

x= 18/9

x= 2

d)  -4a-20= -12a+12

- 4a + 12a =12 + 20

8x = 32

x= 32/8

x= 4
