Question

Answer with detail please

7x - (-2)= 30

m/-2 + (-6)=13

34=9- w/-2

Answer 1

STEP-BY-STEP SOLUTIONS:

Equation No. 1 -

7x - ( - 2 ) = 30
7x + 2 = 30
7x = 30 - 2
7x = 28
x = 28 / 7
x = 4

Equation No. 2 -

m / - 2 + ( - 6 ) = 13
m / - 2 - 6 = 13
m / - 2 = 13 + 6
m / - 2 = 19
m = 19 / - 2
m = - 19 / 2

Equation No. 3 -

34 = 9 - w / - 2
- w / 2 = 34 - 9
- w / 2 = 25
- w = 25 / 2
w = - 25 / 2
