7(3x +4)= 8(2x +5) +13 [use the distributive property to multiply]
21x+28=16x+40+13 [combine like-terms if possible]
21x+28=16x+53 [solve for the x-term]
21x-16x+28=16x-16x+53
5x+28=53
5x+28-28=53-28
5x=25
5x/5=25/5
x=5
.
check by plugging (x=5) back into the orignial eqution and solve]
7(3x +4)= 8(2x +5) +13
7[3(5) +4]= 8[2(5) +5] +13
133=133 [checks out]
