Answer:
Step-by-step explanation: if you are doing subtitution then
Let's solve your system by substitution.
y=4x+14 and y=6x+8
Rewrite equations:
y=4x+14;y=6x+8
Step: Solvey=4x+14for y:
y=4x+14
Step: Substitute4x+14foryiny=6x+8:
y=6x+8
4x+14=6x+8
4x+14+−6x=6x+8+−6x(Add -6x to both sides)
−2x+14=8
−2x+14+−14=8+−14(Add -14 to both sides)
−2x=−6−2x−2=−6−2
(Divide both sides by -2)
x=3
Step: Substitute3forxiny=4x+14:
y=4x+14
y=(4)(3)+14
y=26(Simplify both sides of the equation)
Answer:
x=3 and y=26
Answer:
x = 3
y = 26
( 3, 26)
Step-by-step explanation:
y= 4x + 14
y=6x+8
You can use substitution
4x + 14 = 6x + 8
Subtract 8 on both sides
4x + 14 - 8 = 6x + 8 - 8
4x + 6 = 6x
Subtract 4x on both sides
4x - 4x + 6 = 6x - 4x
6 = 2x
Divide by 2 on both sides
6/2 = 2x/2
3 = x
Now that you have x you can use that to find y
y = 6x + 8
y = 6(3) + 8
y = 18 + 8
y = 26
x = 3
y = 26
( x, y )
