Question

Solve the following equations.
a) x+5=12
b) x-9=13
c)3a=21
d) 7(m+3)=49

class 7​

Answer 1

Step-by-step explanation:

a)x+5=12

x=12-5=7

b)x-9=13

x=13+9=22

c)3a=21

a=21/3=7

d) 7(m+3)=49

m+3=49/7

m=7-3=4

here is ur answer

Answer 2

a) x+5=12

=x=12-5

x=7

b) x-9=13

=x=13+9

x=22

c) 3a=21

=a=12-3

a-9

d)7(m+3)=49

=7m+21=49

=7m=49-21

7m=28

m=28/7

m=4
