Question

How many solutions does this equation have? 7a + 5 (a + 3) = 8a + 4 (a + 2)

Answer 1

Answer:

$no \: solution$

Step-by-step explanation:

1) Expand.

$7a + 5a + 15 = 8a + 4a+ 8$

2) Simplify 7a + 5a + 15 to 12a + 15.

$12a + 15 = 8a + 4a+ 8$

3) Simplify 8a + 4a + 8 to 12a + 8.

$12a + 15 = 12a + 8$

4) Cancle 12a from both sides.

$15 = 8$

5) Since 15 = 8 is false, there's no solution.

$no \: solution$

Therefor, this equation has no solution.
