To solve for m, we must isolate m:
(5-4m)/3 = -7
Multiply both sides by 3:
5-4m = -21
Subtract 5 from both sides:
-4m = -26
Divide by -4:
m = 13/2 = 6.5
-3+x=7. x=10

you do 3 plus 5 first then you get 8 you have to find out what minus 7 equals 8
2x+3 = 7 2x = 7-3 2x = 4 x = 2
Solve for x. 3x + 3 = x + 7 2x + 3 = 7 2x = 4 x = 2 Check it. 6 + 3 = 2 + 7 It checks.

Add 3 to 46 then divide by 7.
you do 3 plus 5 first then you get 8 you have to find out what minus 7 equals 8
2x+3 = 7 2x = 7-3 2x = 4 x = 2
x=-2
-3 + 3 = 0 4 + 3 = 7 7/5 = 1.4 x= 1.4
Solve for x. 3x + 3 = x + 7 2x + 3 = 7 2x = 4 x = 2 Check it. 6 + 3 = 2 + 7 It checks.
25-7=18 18/3=6

3x + 4= 7 3x= 7-4 3x/3 = 3/3 x=1
