Use the distributive property to simplify:
3(x - 5)
3x - 15
combine like terms:
3 + 2x + 5 + 2x
8 + 4x
use the distributive property to simplify:
-2(5 - 2m)
-10 + 4m
x + 5 + 2 = 10
x = 3
combine like terms:
4x - 2 + 6x + 5
10x + 3
1 - 2x = -7x + 6
x = 1
3x + 10 = 4x + 2
x = 8
x + 4 = 4(x + 4)
y = -4
List the steps to solve a multi step equation:
1) Distribute
2) Combine like terms
3) Move the variable
4) Solve
-2x + 7x = -20
x = -4
(2/3)x + 6 = 24
x = 27
(x/3) - (2x/5) = (-7/15)
x = 7
30x + 100 = 50x + 50
x = 2.5
(1/3)x + 6 = (2/5)x - (1/2)
x = 97.5
3(2x + 1) = 8x - 7
x = 5
