Question

How many solutions does a + 3 + 2a = -1 + 3a + 4 have?​

Answer 1

Answer:

Answer is below

Step-by-step explanation:

Simplify both sides of the equation.

$a+3+2a=-1+3a+4\\(a+2a)+(3)=(3a)+(-1+4)\\CLT\\3a+3=3a+3\\3a+3=3a+3$

Subtract 3a from both sides.

$3a+3-3a=3a+3-3a\\3=3$

Subtract 3 from both sides.

$3-3=3-3\\0=0$

All real numbers are solutions

Answer 2

Answer:

the answer is a= -6

Step-by-step explanation:

a + 3a + 2a = -1 + 4 -3

Collect like terms

a - 3a + 2a = -1 + 4 -3

a = -3-3

a = -6
