Question

CAN SOMEONE PLEASEEEE HELLPP

Answer 1

x= -1 and y= 0

Explanation:

These are two simultaneous equations

`y=3x+3` this is equation 1

`-x+2y=1\\` this is equation 2

We can use equation 1 as it is in terms of x and put it in equation 2 which means

`-x+2y=1` becomes

`-x+2(3x+3)=1`

`-x+2(3x+3)=1`

`-x+6x+6=1`

`5x=-5`

`x=-1`

now we know the value of x and to find out the value of y we put the value of x in any equation either number 1 or 2

lets take equation 1

`y=3(-1)+3`

`y=-3+3`

`y=0`

So this is how you solve your equations algebraically
