Answer:
Solution: (1,4)
Explanation:
- 4x - y = 4
y = 2x + 2
We can use substitution
- 4x - 2x + 2 = 4
combine like terms
- 2x + 2 = 4
subtraction property of equality
- 2x + 2 - 2 = 4 - 2
-2x = 2
division property of equality
(-2x)/-2x = 2/2
x = 1
Now you can plug in the value of x into the second equation to find y
y = 2x + 2
y = 2(1) + 2
y= 2 + 2
y = 4
Solution: (1,4)
