Question

The product of 4 and y increased by 5 is equal to the sum of y and 8. Find y

Answer 1

The equation would look like this:

4y+5= 8+y

step 1: begin by combining like terms. I prefer to start with the variables. so, subtract the y (or 1y) from both sides to get 8 alone on the right.

4y+5=8+y

-y -y

3y+5=8

Step 2: Get the variable (and any numbers attached to it) alone. So subtract five from both sides.

3y+5=8

-5 -5

3y=3

Step 3: Get the variable by itself, by removing all attached numbers. Divide both sides by 3.

3y=3

/3 /3

y=1

Extra Step: Always, if able, check your work by plugging it back into the original equation.

4y+5=y+8

4(1) +5= (1) +8

9=9
