Two - step equations:

1) x/2 + 9 = 8
2) 10= -4 + 2/3x

Equations with variables on both sides:

1) 3x + 7 = 2x
2) 3 + 9x + 8 = 6x - 4
3) 3(x + 7) = 15x
4) 2 + 9(x - 2) = 6x + 2

Select all the statements that correctly describe the solutions to this system of equations?
Luba_88 [7]

x + y = 9

x = 9 - y

2x - y = 0

2(9 - y) - y = 0

18 - 2y - y = 0

-3y = -18

y = 6

x = 9 - y

x = 9 - 6

x = 3

HELP PLS!!! I GIVE BRAINLIEST

Based on the multiplication property of equality, the statement that completes the proof is: C. CD = b(sin A) and CD = a(sin B).

<h3>What is the Multiplication Property of Equality?</h3>

The multiplication property of equality is given as, if a/b = y, then a = yb. Both sides of the equation is multiplied by the same value.

In step 5 where the multiplication property of equality is applied, we would have:

sin(A) = CD/b

Multiply both sides by b

sin(A) × b = CD/b × b

b(sin A) = CD

CD = b(sin A)

This same property is applied to sin B = CD/a to get CD = a(sin B).

Therefore, the missing statement is: C. CD = b(sin A) and CD = a(sin B).
