Distribute across the parenthesis then solve for x

Explanation:

# 2(7-x) = 14 - 2x#
# 3 (x +3) = 3x +9 #

so putting these values into the equation gives

# 14- 2x = 3x+9# subtract 9 and add + 2x to both sides.

# 14-9 -2x +2x = 3x + 2x + 9 -9 # which gives

# 5 = 5x # divide both sides by 5 gives

# 5/5 = (5x)/5 # gives

# 1 = x #
