Solve for y means isolate y.
7x + 4y = 8
4y = -7x +8
y = -7/4x + 2
Answer:
9
Step-by-step explanation:
The rules that you need to know for this question are:
- & - = +
+ & - = -
+ & + = +
So for this question we have 16 + -7 so we need to use the + & - rule. Therefore a plus and a minus make a minus so we do 16-7 which is 9
14x+2=12x
[subtract 2 on both sides]
14x=12x-2
[subtract 12x on both sides]
2x=-2
[divide 2 on both sides]
x=-1
Answer:
-2
