How do you solve #7- 4( x + 1) = - 1#?

Answer 1

Kennedy Adams

#x=1#

First, subtract #7# from both sides. You get

#-4(x+1)=-8#

Next, divide both sides by #-4#. You get

#x+1=2#

Subtract #1# from both sides.

#x=1#

To solve the equation 7 - 4(x + 1) = -1:

Distribute the -4: 7 - 4x - 4 = -1
Combine like terms: 7 - 4 - 4x = -1
Simplify: 3 - 4x = -1
Subtract 3 from both sides: 3 - 3 - 4x = -1 - 3
Simplify: -4x = -4
Divide both sides by -4: (-4x)/(-4) = (-4)/(-4)
Simplify: x = 1
