Question

Soo-Jung used the subtraction property of equality to solve an equation for y. Which equation could be the one that Soo-Jung solved? 4 y = 12 StartFraction y Over 4 EndFraction = 12 2 (4 y) = 12 y + 4 = 12

Answer 1

Answer:

D y + 4 = 12

Explanation:

I just took the quiz and got 100

Answer 2

Explanation:

Option 1.

4y=12

Dividing 4 both sides

y=3

Division property should be used.

Option 2.

$\dfrac{y}{4}=12$

Cross multiplying each other,

y=12(4)

y=48

Option 3.

2(4y)=12

Opening bracktet in LHS

8y=12

Dividing both sides by 8 i.e.

$y=\dfrac{12}{8}\\\\y=\dfrac{3}{2}$

Division property is used.

Option 4.

y+4=12

Subtracting both sides by 4 i.e.

Y+4-4=12-4

y=8

Subtraction property is used.

It means that in option (4) Soo-Jung used the subtraction property of equality to solve an equation for y.
