Liayh spends \$45 on VANS. This was \$15 less than twice what she spent for a black dress. How much was the black dress? 2x-15 = 45 >>>>> Move the constant to the right 2x = 42 + 15 >>>>> Add the numbers 2x = 60 >>>>>> Divide both sides by 2 X= 30
Liyah has three clients that are sisters. The older sister is one year more than twice her age. The younger sister is three years younger than her. The sum of their ages is 28. Find the age of the youngest. 2a + 1 + a + 3 + a = 28 >>>>> like terms 4a + 4 = 28 >>>>>> Move constant to the right 4a = 28 – 4 >>>>>> Subtract the numbers 4a = 24 >>>> Divide both sides by 4 a = 6

I want to buy some new bundles while searching all the different bundles Online I have a \$15 off coupon for bundles. Once I choose the bundles I Want I see there’s a 20% off for the bundles. I must choose which will save me more the coupon or the 20% discount Equation: a – 15 = a – 0.20a >>>>> Cancel equation terms -15 = -0.2a >>> Swap the sides -0.2a = -15 >>> Divide both sides by -0.2 A = 75 I can use the coupon or the 20% discount it would be the same.
