find the value for "x"

$2x-3+3x=90$

add 3 to both sides

$2x+3x=90+3$

collect terms

$5x=93$

divide by 5

$x=\frac{93}{5}$

ta dah!

oh okay - derp moment there

just put $\frac{5}{95}$instead of $\frac{3}{95}$

which cancels to $\frac{1}{19}$

2x-3+3x-2=90  combine like terms on the left

5x - 5  = 90      add 5 to each sides

5x  = 95          divide both sides by 5

x = 19
