Question

1. 3(x+4)=-2(x+5)
2.5x+9-7x-10=3x+4(x+2)

Answer 1

1. = x + 2

Answer 2

whats X?? for #1 I don't understand how to solve these problems

Answer 3

It's called expanding brackets. You do 3 times x which = 3x, then 3 times 4 which = 12. Then you do -2 times x which = -2x, and then -2 times 5 which = -10. Finally you add all of these factors together, giving you an answer of x + 2

Answer 4

\[3x+12=-2x-10\] try this
