3m+2=17 First, subtract 2 to get m on one side. 3m+2-2=17-2 3m=15 Divide by 3 to get m by itself. 3m/3=15/3 m=5 m equals 5.

3m + 10 = 12 - m add m to both sides: 4m + 10 = 12 subtract 10 from both sides: 4m = 2 divide both sides by 4: m = 2/4 = 1/2 or 0.5

(10-2)x180=1440 Degrees You first have to subtract 10 - 2 then multiply by 180

You would usually associate total with add. However getting a total can sometimes involve having to subtract something.

Equation 1: M = L + 24; Equation 2: M + 2 = 2(L + 2) Substitute M: L + 24 + 2 = 2L + 4 Subtract L from each side: 26 = L + 4 Subtract 4 from each side: 22 = L Max is 46 and Liam is 22; in 2 years Max will be 48 and Liam 24.

By the signs: 2+2(Add) 2-2(Subtract) +=add -=subtract

1. Subtract 25 2. Then subtract 6 3. Then subtract 12 4. Then subtract 2 5. Then subtract 10 6. Then subtract 15 7. Then subtract 7 8. Then add 3 X 1/2 9. Then add 8

subtract 1 from 2

mn = 80 m -n = -79 Substitute m - 80/m = -79 m^2 - 80 = -79m m^2 + 79m = 80 (NB Notice change of signs) Quadratic Eq'n m = { - 79 +/- sqrt[)79)^2 - 4(1)(-80)}] / 2(1) m = { - 79 +/- sqrt[6241 + 320}]/ 2 m = { -79 +/- sqrt[6561]} / 2 m = { - 79 +/- 81}/2 m = -160 / 2 = -80 or m = 2/2 = 1 Hence n = 1 + 79 = 80
