The solution is -5

Work Step by Step

5x-3 =2x-18 Add 3 to both sides 5x-3 +3=2x-18 +3 Simplify 5x= 2x -15 Subtract 2x from both sides 5x-2x=2x-15-2x Simplify 3x= -15 Divide both sides by 3 $\frac{3x}{3}$=$\frac{-15}{3}$ x=-5 The solution is -5 Check 5x-3 =2x-18 5(-5)-3 =2(-5)-18 -25-3 = -10-18 -28=-28
