Solve 5x + 3 = 18 for x.
Answer (1)
x = 3In this activity, we're going to solve the equation [tex]\sf 5x+3=18[/tex].Step 1: Subtract 3 from both sides.→ [tex]\sf 5x+3=18[/tex]→ [tex]\sf 5x=18-3[/tex]→ [tex]\sf 5x=15[/tex]Step 2: Divide both sides by 5.→ [tex]\sf \cfrac{5x}{5}=\cfrac{15}{5}[/tex]→ [tex]\sf x=3[/tex]
