Q:
# 3(1 - 3x) = 2(- 4x + 7) solve

Accepted Solution

A:

Answer:x=-11Step-by-step explanation:3(1-3x)=2(-4x+7)1) Distribute 3 to 1 and -3x:3-9x=2(-4x+7)2) Distribute 2 to -4x and 7:3-9x=-8x+143) Subtract 3 from both sides::-9x=-8x+114) Add 8x to both sides:-1x=115) Divide both sides by -1:x=-11Footnotes:-The Distributive property says a(b+c)=ab+ac-When you have a negative variable, there is an implied (-1) before the variable :)
