Question

Solve for x: -2(x + 3) = -2(x + 1) - 4.

2

3

All real numbers

No solution

Answer 1

-2(x + 3) = -2(x + 1) - 4 distribute
-2x - 6 = -2x - 2 - 4 add like terms
-2x - 6 = -2x - 6 add 2x to both sides
+2x +2x
-6 = -6
-6 does equal -6
therefore "all real numbers"

but keep in mind that if it was something like 2 = 5
2 does not equal 5 so "no solution"

Answer 6

Solve for x: 3 over 4 x + 5 over 8 = 4x

x = __________________ Write your answer as a fraction in simplest form. Use the "/" symbol for the fraction bar.

Answer 7

(3/4)x + (5/8) = 4x make your life easier, multiply everything by 8
6x + 5 = 32x then subtract both sides by 6x
-6x -6x
5 = 26x divide both sides by 26
