Question

Y=x+3
y=2x-4
what would x and y be as a coordinate point​

Answer 1

X=7,y=10

Explanation:

This simultaneous equation requires substitution method

So let's solve

Y=X+3....(1)

Y=2x-4...(2)

X+3=2x-4

Collect like terms

X-2x=-4-3

-x=-7

Divide both sides by-

x=7

Let substitute the value of x in (2)

Y=2(7)-4

Y=14-4

Y=10

When x is 7,y is 10

Answer 2

(7,10)

Explanation:

Since both equations are equal to y, we can set them equal

y=x+3

y=2x-4

x+3 = 2x-4

Subtract x from each side

x+3-x =2x-4-x

3 = x-4

Add 4 to each side

3+4 =x-4+4

7 =x

Now we need to find y

y = x+3

y =7+3

10
