Answer:
y = -8
Step-by-step explanation:
If the equation is parallel to y = 9, the you already know that the equation must be y = some value. It passes through the point (3,-8). Just put that y value into the equation to get y = -8
Answer: 70s - 70
Step-by-step explanation:
Answer:
4x-20 is the same as x+x+x+x-20
Let x be the first number and y be the second.
2x + y = 25
3x - y =20
1) Add them together.
5x = 45
x = 9
2) Solve for y.
2(9) + y = 25
y=7
3) Check your work on the other equation.
3(9) - (7) = 20
27 - 7 =20
20 = 20
