Answer:
x = 7.9
Step-by-step explanation:
-2.3x + 4.2x = 15.01
combine like terms
1.9x = 15.01
divide both sides by 1.9
x = 7.9
Substitue y=3x+2 to the y in y=x+10.
3x+2= x+10
Subtract 2 to both sides.
3x=x+8
Subtract x to both sides.
2x=8
Divide both sides by 2
2x/2 = 8/2
You are left with x = 4
Choose one equation and replace x by 4.
y = (4) + 10
y= 14
Now, you have x = 4 and y= 14. So, your ordered pair is (4,14) because both lines pass through that point.
If you do not want to do this solution, I suggest you graph it using the slope.
