Question

Solve:
a) 5m+7=17 b) 0=15+3(m-2)
Write the equation for the following:
a) if you add 3 to one thirdnof m , you get 30
b)three fourth of x is 20

Answer 1

1). 5m =10
m=2

2) 0= 15+3m-6
-9=3m

m= -3


3 +m/3 =30

its equation become
a) 9+ m=90
b) 3x -80

Answer 2

SOLVING


a)5m+7=17
or 5m=17-7
or 5m=10
or m=2

b) 0=15+3(m-2)
or 0=15+3m-6
or 0=9+3m
or 3m=9
or m=3

EQUATIONS

a)1/3m=30
b)3/4x= 20
