7e-4=31 add 4 to both sides = 7e=35 then divide 7 on both sides then you get the answer of e=5
solve your equation step-by-step.
7x−4=31
Add 4 to both sides.
7x−4+4=31+4
7x=35
Divide both sides by 7.
7x/7 = 35/7
x=5
7x−4=31
Add 4 to both sides.
7x−4+4=31+4
7x=35
Divide both sides by 7.
7x/7 = 35/7
x=5
