Hello Savanna
y=3x-4
2x+4y=26
Can we solve it together ? :) Thx
We need to solve y=3x-4 for y
Now let's start solving this by substitute 3x-4 for y in 2x+4y=26
2x+4(3x-4)=26
14x-16=26
Now let's add 16 to both sides
14x-16+16=26+16
14x=42
Divide both sides by 14 so we can find the value for x
14x/14= 42/14
x=3
Good job:) now we find the value of x
We are not done yet.
Let's find the value for y by substitute 3 for x in y=3x-4
y=3x-4
y=(3)(3)-4
y=9-4
y=5
Yeah well done :)
Final answer : x=3 and y=5
(3,5)
Was that helped ? please rate my answer :0
