When solving for “x” which is a variable, you want to look at other numbers, and components in the expression. The goal is to get x by itself in an equation. For example, x+2=10. Here you would subtract 2 from both sides and get x=8. Hope this helps.

Answer from: Quest

the solution is the point (1,-3)

step-by-step explanation:

we have

3x-y=6 > equation a

y=x-4 > equation b

adds equation a and equation b

3x-y=6\\y=x--y+y=6+x-4\\3x=2+x\\3x-x=2\\2x=2\\x=1

substitute the value of x in equation b to find the value of y

y=(1)-4=-3

the solution is the point (1,-3)
