Question

Which expression is equivalent to 5(y + 3) + 9? please help

Answer 1

Answer:

I’ll try my best:

x + y = ; x + 2y = 11

(add y to both sides)

(substitute each and simply each side)

(add -7)

-y + 7 = 11

(simplify both sides)

y + 7 + -7 = 11 + -7

y=4

x= -y + 7

(simplify)

ANSWER:

x=3

y=4
