Question

Now let’s practice what you have learned.


Solve the equation.
4y – 4 = 28

Answer 1

y = 8

Explanation:

4y - 4 = 28

take -4 to the equal side, which will change and become +4

so, it will be; 4y = 28 + 4

4y = 32

divide both sides by the number next to the unknown(y), which is 4

y = 8

Answer 2

y=8

Explanation:

4y-4=28

4y=28+4

4y=32

y=32/4

y=8

now plug in 8 for y and check the equation true:

4y-4=28

4*(8)-4=28

32-4=28

28=28

So, y is equal to eight 8
