Question 212817
Solve:
1).
{{{2x+4 = x-5}}} Subtract x from both sides.
{{{x+4 = -5}}} Subtract 4 from both sides.
{{{highlight(x = -9)}}}
2).
{{{3x-5 = 5-(x+1)}}} Simplify the right side.
{{{3x-5 = 5-x-1}}} Add x to both sides.
{{{4x-5 = 5-1}}} Add 5 to both sides.
{{{4x = 5+5-1}}} Simplify the right side.
{{{4x = 9}}} Divide both sides by 4.
{{{highlight(x = 9/4)}}}
