Simplify the following expression. 5(4 + 3c) - 12

5(4 + 3c) - 12 = 15c + 8

Step-by-step explanation:

1st step, expand it to make it a little easier to solve, 20 + 15c - 12

2nd step, subtract, 20 - 12 = 8

3rd step simplify, 15c + 8

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
