Malloy solved the equation −5x − 16 = 8; his work is shown below. Identify the error and where it was made. −5x − 16 = 8
Step 1: −5x − 16 + 16 = 8 + 16
Step 2: −5x = 24
Step 3: negative five times x over five = twenty-four over five
Step 4: x = twenty-four over five

Step 1: He should have subtracted 16 from each side.
Step 1: He should have divided both sides by −5.
Step 3: He should have multiplied both sides by −5.
Step 3: He should have divided both sides by −5.

He should have divided both sides by - 5.

Step-by-step explanation:

-5x=24

-5x/5=24/-5

X= -24/5

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
