Question

A) 4(x+1)=5x+12

B) 13(6 –x) –4(3x+12)=0

C) 9(2x+7)=0.5(32x+6)

D) 8x –3(5x–2)=7–10x

Solve for x

Answer 1

A.
4x+4=5x+12
4=x+12
x=-8

B.
13(6-x)-4(3x+12)=0
78-13x-12x-48=0
30-25x=0
25x=30
x=1.2

C.
9(2x+7)=0.5(32x+6)
18x+63=16x+3
2x+63=3
2x=-60
x=-30

D.
8x –3(5x–2)=7–10x
8x-15x+6=7-10x
-7x+6=7-10x
3x=1
x=1/3

So, A = -8 B = 1.2 C = -30 and D. = 1/3

Answer 2

Hey there!

Here is ur answer >>>>

A) 4(X + 1 ) = 5x + 12

4x + 4 = 5x + 12

X = 4 - 12

X = -8

B) 13 ( 6 - x ) - 4 ( 3x + 12 ) = 0

78 - 13x - 12x - 48 = 0

30 - 25x = 0

30 = 25x

X = 30/25

X = 6/5

All of them are solved in these methods
