To start take the equation and then plug in 9 for x
3x+4y=43
3(9)+4y=43
27+4y=43
Subtract 27 from each side to get all of the y's by themselves
27+4y-27=43-27
4y=16
Divide by four to get the value of one y
4y/4=16/4
y=4
Answer:
2+2 equals 4
Step-by-step explanation:
Answer:
The first answer choice, (-14) + 8
Step-by-step explanation:
1. Solve (-14) - (-8)
