2x + 12 = 3 - x what is the answer
Answers
Answer:
Rearrange terms
2+12=3−
2x+12={\color{#c92786}{3-x}}2x+12=3−x
2+12=−+3
2x+12={\color{#c92786}{-x+3}}2x+12=−x+3
2
Subtract
12
1212
from both sides of the equation
2+12=−+3
2x+12=-x+32x+12=−x+3
2+12−12=−+3−12
2x+12{\color{#c92786}{-12}}=-x+3{\color{#c92786}{-12}}2x+12−12=−x+3−12

3=−9
3x=-93x=−9
6
Divide both sides of the equation by the same term
3=−9
3x=-93x=−9
33=−93
\frac{3x}{{\color{#c92786}{3}}}=\frac{-9}{{\color{#c92786}{3}}}33x=3−9
