-3+x=7. x=10
-3
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.
