5(2x+1)=2x+21
Multiply 5 times (2+1)
10x+5=2x+21
Subtract -2x from 10x
10x - 2x = 8x
8x+5=21
Subtract 5 from 21
21 - 5 = 16
8x=16
Divide 16 by 8
16 / 8 = 2
x = 2
Answer: x=2
kaleidoscope; live
5(2x + 1) = 2x + 21
Multiply the 5 into (2x + 1)
10x + 5 = 2x + 21
Subtract 2x on both sides to get the "x" on one side of the equation
8x + 5 = 21
Subtract 5 on both sides
8x = 16
Divide 8 on both sides to get "x" by itself
x = 2
