X+7=-8
You are trying to get x on its own so you will subtract 7 from both sides.
x+7-7=-8-7
This simplifies to x= -8-7
A negative plus a negative equals a negative. So -8-7 equals -15
Your final answer is x=-15
-3/8(2)= -.75 which is -3/4
40 out of 250 students speak French: 40 / 250 = 0.16

x = y + 2, so
(x) = x + 2
