You would set the equations equal to eachother and get x=-5/4 and then plug that in for x, i hope this helps!
On the left side, distribute the 2 to x and -3 so the left side should look like 5x+2x-6.
on the right, distribute the -2 to x and -1 so the right side should look like -2x+2.
combine like terms on the left to get 7x-6=-2x+2
add -2x from the right side to the left side to make the equation 9x-6=2 now it's a two step equation.
add 6 to 2 to get 9x=8. divide by 9 and x=8/9.
