Answer:

m\angle ABC+\angle CBD=m\angle ABD

\longrightarrow (3x+33)+(5x+13)=70

\hookrightarrow 8x+46=70

\hookrightarrow 8x=70-46

\hookrightarrow 8x=24

\hookrightarrow x=24/8=3

so, m\angle ABC=3(3)+33=42

<u>-----------------------</u>

Hope it helps...

Have a great day!!

Answer:

42

Step-by-step explanation:

ABC + CBD = ABD

3x+33 + 5x+13 = 70

Combine like terms

8x +46 = 70

Subtract 46 from each side

8x+46-46 = 70-46

8x = 24

Divide each side by 8

8x/8 = 24/8

x=3

We want to find ABC

ABC = 3x+33 = 3*3 +33 = 9+33 = 42

3x+2=5x What is the answer for this solving equations with variables on each side
Yanka [14]
3x +2= 5x
-3x
2= 2x
/2
1= x
So first I got all the x’s on one side and the whole numbers on the other side. So we had 2 on one side and 2x on the other. From there we divided by the number of x’s which was 2 so we can get one x only. So 2/2= 1 so x =1
