.y=x+2
y = 2x - 5
How do we solve this

X=7

Y=9

Step-by-step explanation:

.y=x+2

y = 2x - 5

Use equivalents y=y so you get:

X+2=2x-5

X-2x=-5-2

-x=-7

X=7

Y=x+2=7+2=9

x=7 and y=9

Step-by-step explanation:

y=x+2

y=2x-5

Rearrange we get

x-y=-2

2x-y=5

Solve simultaneously we gets

Using elimination method

-x=-7

x=7

Substitute for x in equation I

x-y=7

7-y=-2

y=9
