b)+2x=+10
c)+4x=+24
d)+x+3=+8
e)+x-2=-1
f)+2y+1=-8
g)+7x=4x+5
h)+4x=+3x+9
i)+5×+1=+16

Answer 1

a) +8y=-8

y = -8/8

y = -1

b)+2x=+10

x = 10/2

x = 5

c)+4x=+24

x = 24/4

x = 6

d)+x+3=+8

x = 8-3

x = 5

e)+x-2=-1

x = -1+2

x = 1

f)+2y+1=-8

2y = -8-1

2y = -9

y = -9/2

g)+7x=4x+5

7x-4x = 5

3x = 5

x = 5/3

h)+4x=+3x+9

4x-3x = 9

x = 9

i)+5×+1=+16

5x = 16-1

5x = 15

x = 15/5

x = 3
