a) 2(5x-3)=24
*Distribute the 2*
10x-6=24
*Add 6 to both sides*
10x=30
*Divide both sides by 10*
ANS: x=3
b) 5(2x+1)=50
*Distribute the 5*
10x+5=50
*Subtract 5 from both sides*
10x=45
*Divide both sides by 10*
x=45/10
*Simplify by dividing numerator and denominator by GCF (5)
ANS: x=9/2
Hope this makes sense!
