Humberto evaluates the expression 4 t 2 for t=3. He correctly substitutes 3 for t in the expression, but then says that the value is 144. However, he is incorrect! Can you identify what he may have done wrong? 1. What is the correct value of the expression?
2. Stating the rules of order of operations, what must be simplified first? What is then simplified second?
Answer these questions in a few sentences or use numerical equations to demonstrate your work.

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
