Answer:
[tex]-\frac{4}{3},\frac{14}{3}[/tex]
Step-by-step explanation:
1) Break down the problem into these 2 equations.
−3a+5=9
−(−3a+5)=9
2) Solve the 1st equation: −3a+5=9.
1 Subtract 5 from both sides.
−3a=9−5
2 Simplify 9−5 to 4.
−3a=4
3 Divide both sides by −3.
a=[tex]-\frac{4}{3}[/tex]
3 Solve the 2nd equation: −(−3a+5)=9.
1 Remove parentheses.
3a−5=9
2 Add 5 to both sides.
3a=9+5
3 Simplify 9+5 to 14.
3a=14
4 Divide both sides by 3.
a=[tex]\frac{14}{3}[/tex]
4 Collect all solutions.
a=[tex]-\frac{4}{3},\frac{14}{3}[/tex]
