How do you solve #-8(4+9x)=7(-2-11x)#?

Answer 1

#x = 18/5#

Remove the brackets first.

#" "-8(4+9x)=7(-2-11x)# #" "-32-72x = -14-77x# #" "77x -72x = -14+32 larr # variables on one side. #" "5x = 18 larr # simplify

#" "x = 18/5#

To solve the equation -8(4+9x)=7(-2-11x), you can follow these steps:

Distribute the numbers outside the parentheses: -84 + (-8)9x = 7(-2) + 7(-11x)
Simplify each side: -32 - 72x = -14 - 77x
Combine like terms on each side: -32 + 14 = -77x + 72x
Solve for x: -18 = -5x
Divide both sides by -5: x = 18/5

So, the solution to the equation is x = 18/5.
