Question

3(4y-5)+6(-5+9)...... the answer i came out with was 12y
can someone tell me if I did it right?

Answer 1

if this is just an expression, the answer is 12y + 9
but if this is an equation, the answer is -3/4

Answer 2

how did you get the +9?

Answer 3

it goes like this:
3(4y-5)+(-5+9)
12y-15-30+54
12y+9
or if this is an equation it goes like this:
12y+9=0
12y=-9
y= -3/4

Answer 4

*3(4y-5)+6(-5+9)

Answer 5

okay got it.... thank you :)

Answer 6

check the value when you multiplied 6 to 9. 6 multiplied to 9 is equal to 54

Answer 7
