3x + 2y = 8To solve P amount of variables, you need P equations. (e.g., for this problem you'd need two equations to actually solve for it.) However, with that said, there are an infinite amount of solutions that "work".First, solve for one of the variables. People are typically use to y=... form so:3x + 2y = 82y = 8 - 3xy = (1/2)(8-3x)y = 4-(3/2)x

x = 59y = 23Let:x = the first numbery = the second numberx + y = 82 -- equation (1)x - y = 36 --- equation (2)By Elimination:x + y = 82x - y = 36=========2x = 118 2x/2 = 118/2x = 59x + y = 82y = 82 - xy = 82 - 59y = 23check:x - y = 3959 - 23 = 3636 = 36Let x = 1st numberlet y = 2nd numberX + Y = 82X - Y = 36add above equations2X = 118X = 59Y = 23

it is 28

it equals 167.40

It equals 24.

5 plus 25 equals 60. Need to solve for 5 plus 25 equals ?: 2 plus 10 equals 24 is equivalent to 2 × (1 plus 5) equals 2 × (12); and 3 plus 15 equals 36 is equivalent to 3 ×(1 plus 5) equals 3 × (12); thus 5 plus 25 equals ? is equivalent to 5 × (1 plus 5) equals 5 × (12); thus ? = 5 × 12 = 60.
