To substitute, solve for one variable and then plug it into the other equation you have. In this problem, y is already solved for on the top equation (y=x+2), so you just stuff it into the second equation.
y = x + 2
3y = 4x - 2
3(x + 2) = 4x - 2
3x + 6 = 4x - 2
-x = -8
x = 8
y = x + 2 = 8 + 2 = 10
solution:
x = 8
y = 10
hope this helps!! :)
Answer: -1x - 1
Step-by-step explanation:
2 -1x -3
2-3 = -1
-1x - 1
Answer:
The answer is y=5x²
Step-by-step explanation:
If you put y=5x² on a graph paper it will be in a staright line.
Answer:
d = -19
Step-by-step explanation:
64 = -3d + 7
Subtracting 7 on both sides,
64-7 = -3d
57 = -3d
Divide both sides by -3,
d = -19
Divide both numbers by a common multiple which will give you: 1/3
