Question

A-12 10

Answer 1

Answer:

a = 76/3

Step-by-step explanation:

I completely understand your frustration. Algebra 2 is also painful for me this year.

1. Since these equations are equal to each other, you can cross multiply them and set those equal to each other: (a -12) • 3 = 4 • 10.

2. Solve: (a-12) • 3 = 4•10

3a-36 = 40

3a=76

a= 76/3.

(Is this supposed to be a whole number?)

Answer 2

You need to get the variable by itself, meaning no fractions, multiplication, and no negative signs.
