Answer:
Step-by-step explanation:
1. -3( x - 4) = 2x + 4 - x
-3x + 4 = x + 4
4 = 2x + 4
2x = 0
x = 0
2. 4 + 2 (x - 2) = 2 (x - 1) + 2
4 + 2x - 4 = 2x + 2 + 2
2x = 2x + 4
x = 4
3. 3(x - 4) = 2x - 7 + x
3x - 12 = 3x - 7
x = 5
4. 4x + 15 = 3(x + 5)
4x + 15 = 3x + 15
x = 0
5. 2(x - 3)
for the rest i'm confuse what it is suppose to be
Because you increased by the percent THEN decreased by a different percent, you subtract both percents because they are of like terms. So you do 45%-20% which equals 25% which is what’s left after dropping the total.
