Question

1. Solve the equation.
y + 13 = 10
A.
y = 3
B.
y = -23
C.
y = 23
D.
y = -3

2. Solve the equation.
9 = x - 3
A.
x = -6
B.
x = 12
C.
x = 6
D.
x = -12

3.
Y = 2 is a solution to the equation 3y = 12
A.
True
B.
False

Answer 1

Well for the first one, you'd have to subtract 13 from both sides, so you'd get y=-3 as your answer.

Answer 2

The second one would be x=12 because by adding the 3 to both sides, you'd cancel out the -3 and the 9 would become 12.

Answer 3

The last one would be false because to solve 3y=12, you'd have to cancel out the 3 by dividing 3 to both sides which leaves you with y=4 :)

Answer 4

thanks soo much i thot that but i didnt no

You're very welcome! Glad to be able to help :)
