How do you solve #3x = - 3( 4x + 10)#?

Question:

How do you solve #3x = - 3( 4x + 10)#?

Answers

#x = -2#

Explanation:

Step 1) Expand the terms within parenthesis, in this case just the right side:

#3x = -12x - 30#

Step 2) Solve for #x# by isolating #x# using the necessary mathematics while keeping the equation balanced:

#3x + 12x = -12x - 30 + 12x#

#15x = 0 - 30#

#15x = -30#

#(15x)/15 = -30/15#

#1x = -2#

#x = -2#
