Answer:
Step-by-step explanation:
To better understand the question we need to properly format the expression
as we can see we have three brackets, we can proceed by first opening the first two brackets, we have.
we then continue by collecting like terms
we then solve for the remaining two brackets
we then continue by collecting like terms
from the two brackets we obtained each, we now have to multiply both terms together and solve we have
collecting and summing all like terms we have
Answer:
Simplifying
4x + 9 = 12x + -3
Reorder the terms:
9 + 4x = 12x + -3
Reorder the terms:
9 + 4x = -3 + 12x
Solving
9 + 4x = -3 + 12x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-12x' to each side of the equation.
9 + 4x + -12x = -3 + 12x + -12x
Combine like terms: 4x + -12x = -8x
9 + -8x = -3 + 12x + -12x
Combine like terms: 12x + -12x = 0
9 + -8x = -3 + 0
9 + -8x = -3
Add '-9' to each side of the equation.
9 + -9 + -8x = -3 + -9
Combine like terms: 9 + -9 = 0
0 + -8x = -3 + -9
-8x = -3 + -9
Combine like terms: -3 + -9 = -12
-8x = -12
Divide each side by '-8'.
x = 1.5
Simplifying
x = 1.5

Answer:
y=2
Step-by-step explanation:
-(3y+2) -(-2y-4)=0
Distribute the minus signs
-3y -2 +2y +4 = 0
Combine like terms
-y +2 = 0
Add y to each side
-y+y +2 = 0+y
2=y
Check
-(3*2+2) -( -2*2-4) =0
-(6+2) -(-4-4)=0
-8 - (-8) =0
-8+8 =0
0=0
