Answer:
x=28
Step-by-step explanation:
-7(3+6x)=9(-5x+7)
-21-42x=-45x+63
-21-42x-(-45x)=63
-21-42x+45x=63
-21+3x=63
3x=63-(-21)
3x=63+21
3x=84
x=84/3
x=28
The last graph is the answer
Answer:
X = 108.
Step-by-step explanation:
Heights are equal, So equation will be,

So, solving the eq.
Subtract 4 from both sides ,

Divide 3 to both sides,

Squaring both sides,

Add 8 to both sides,

Answer:
Step-by-step explanation:
i think its 500%
but im not sure
because 20 divided by 4 = 5
and 5.0 = 500%
X + (-y) = -2.3 + ( - (-5.9) ) = -2.3 + 5.9 = 3.6
