Khan Academy is popular among students, parents, and educators because its videos are engaging and targeted at visual learners, using photos, maps, and other illustrations, and it also allows students to work at their own pace. How old is Imran right now? He is 4 years old. We are left with x isĮqual to 4 years old. And you could do this inīy 10, but we've got to do that to both sides. So I'm left with 10 times x isĮqual to- well, these x's, x minus x is just 0. If I have 11 of something and I take away 1 of them, I'm This x on the right hand side, I'd want to subtract an x. Right now is how old he is going to be in 40 years. Going to be 11 times as old as he is right now. Quantity right over here, x plus 40, is going This by itself isn'tĮnough to figure out how old he is right now. Going to be x plus 40, plus this 40 right over here. Old he will be in 40 years? Well, he's going to be ![]() ![]() How old is he right now? And so I encourage you getģ(j-4) = 2(j+5), work through distributive propertyģj = 2j + 22, subtract 2j from both sides (1/2)(j-4) = (1/3)(j+5), I would multiply both sides by 6 to eliminate all the fractions. (1/3)p = 9, multiply both sides by 3 to eliminate fraction, getĢ.A half of what John's age was 4 years ago is(=) equal to one third of what it will be in 5 years' time.How old is John now? (4/3)p = p + 9, subtract p from both sides, get (4/3)p - 4 = p + 5, add 4 to both sides, get (m-2)=(1/2)*(p+5), multiply 2nd eqn by 2 to eliminate fraction, so system isĢm - 4 = p + 5, substitute value of m from 1st eqn into 2nd eqn, getĢ((2/3)p) - 4 = p + 5, solve for p. Define m as Mary's age, p as Peter's age, convert the problem into algebra notation.ġ.Mary's age (m) is(=) 2/3 that of Peter's((2/3)*p).Two years ago Mary's age(m-2) was(=) 1/2 of what Peter's age will be in 5 years' time.How old is Peter now?
