45 = 30 + m Subtract 30 from both sides: 15 = m

v is -15... -15*2 = -30... -30+11= -19.

90+x+72+30 = 180. If you add 90+72+30, you get 192. But to get 180 you have to subtract 12. 90+(-12)+72+30 =180 if x is -12

x2 + 13x = -30 ∴ x2 + 13x + 30 = 0 ∴ (x + 3)(x + 10) = 0 ∴ x ∈ {-3, -10}

To solve this one, subtract 50 from 180 and you'll have your answer.

v is -15... -15*2 = -30... -30+11= -19.

x = 6 and y = -2

x+30 = 3x-50 x-3x = -50-30 -2x = -80 x = 40

8x+30=4x+18 -4x -4x 4x+30=18 -30 -30 4x=-12 4x/4=-12/4 x=-3

90+x+72+30 = 180. If you add 90+72+30, you get 192. But to get 180 you have to subtract 12. 90+(-12)+72+30 =180 if x is -12

x2 + 13x = -30 ∴ x2 + 13x + 30 = 0 ∴ (x + 3)(x + 10) = 0 ∴ x ∈ {-3, -10}
