Question

Help Please and Thank You!

−5(x + 6) = 15
(A) x = 9
(B) x = 3
(C) x = -9
(D) x = 21//5
(E) x = -21/5

Answer 1

Explanation:

expand the bracke

so -5(X+6) is -5x-30=15

so

-5x-30=15 ( add 30 so that no number in the equation) 15+30 is 45

-5x=45(divide by 5 as 45 is multiple of 5)

45/-5=-9 (positive / negative is negative)

X=-9
