Question

a)9x+9=8x+18

b)3x-4=8

c)9x+5=68

d)5y-8=13

e)7m-10=11
​

Answer 1

a)9x+9=8x+18

9x - 8x = 18 - 9

1x = 9

x = 9

b)3x-4=8

3x = 8 + 4

3x = 12

x = 12 / 3

x = 4

c)9x+5=68

9x = 68 - 5

9x = 63

x = 63 / 9

x = 7

d)5y-8=13

5y = 13 + 8

5y = 21

y = 21 / 5

y = 4,2

e)7m-10=11

7m = 11 + 10

7m = 21

m = 3
