SOMEONE WHO LIKES MATHS OR CAN DO IT PLS HELP COZ THIS IS SO CONFUSING:((. do the ones you know !! I’ll brainlist:)

a) c + y = 10 + 11 = 21

b) q + b + r = -14 + (-7) + (-13) =

= -(14 + 7 + 13) = -34

c) 8x + 3z = 8 · 9 + 3 · 4 = 72 + 12 = 84

d) 6a + 5b = 6 · (-1) + 5 · (-3) = -6 - 15 = -21

e) -9y + 2z = -9 · (-5) + 2 · (-7) = 45 - 14 = 31

f) -3t + 4y + s = -3 · 8 + 4 · (-2) + (-2) =

= -24 - 8 - 2 = -(24 + 8 + 2) = -34

g) y² + c = 4² + 7 = 4 · 4 + 7 = 16 + 7 = 23

h) a² + x = (-10)² + (-8) = 100 - 8 = 92

i) b + 2y² = 2 + 2 · 6² = 2 + 2 · 36 =

= 2 + 72 = 74

j) 3y² - 3z = 3 · 6² - 3 · (-7) = 3 · 36 + 21 =

= 108 + 21 = 129
