Answer:
x=2,y=2
Step-by-step explanation:
This question is a simultaneous equation
So let's solve
3x+y=8...(1)
2x+2y=8....(2)
Multiply (1) by 2
6x+2y=16...(3)
Substrate (2) From (3)
4x=8
Let's make x the subject of formula by dividing both sides by 4
x=2
So let's substitute the value of x into (1)
3x+y=8
3(2)+y=8
6+y=8
y=8-6
y=2
Therefore x is 2,y is 2
Answer:
y=3x+1
Step-by-step explanation:
the y-value increases by 3 each time the x-value increases by 1, so the slope is 3. When the x-value is 0, the y-value is 1, so the y-intercept is 1. The equation is represented as y=mx+b, where m is the slope and b is the y-intercept, so substitute the numbers in and you get y=3x+1
