Answer:
x=-54
Step-by-step explanation:
-4(2x+9)+3x=6-4(x-3)
Reorder the terms in parentheses
+(-8x-36)+3x=6-4*(x-3)
Remove unnecessary parentheses
-8x-36+3x=+6-4+*(+x-3+)
Reorder the terms in parentheses
-8x-36+3x=6+(-4x+12)
Remove unnecessary parentheses
-8x-36+3x=+6-4x+12
move all terms containing x to the left and all other terms to the right.
-8x+3x+4x=+6+12+36
simplify left and right side of the equation.
-1x=+54
finally, divide both sides of the equation by -1 to get x.
x=-54
Add 11 and 7
11 + 7
18
Mulitply 1/3 and 18
1/3 * 18
6
1/3 the sum of 7 and 11 is 6.
