How to solve y=2x-6 y=-3x+4 using substitution

you can put both into a graphic calc if u have one or if not then move the x to the other side for one of the equations.

Step-by-step explanation:

for example, for the seccond equation, you can add 3x on both sides to undo it, since the opposite of subtraction is addition, and the 3x is negative. so then you would be left with 3x + y= 4 so subtract y. the equation should be 3x= -y +4. divide by 3 so you could get x alone. the answer should be x= -1/3y + 4/3. now substitute that new equation into the x for the first equation so you would get y= 2(-1/3y + 4/3) -6. you should get y= -2/3y + 8/3 -6. add the -2/3y to move it to the other side. now you should have 1 2/3y= 8/3 - 6. you could simplify that to 1 2/3y= -3 1/3. divide by 1 2/3 on both sides and you should get that x is  2/3. hope this helps :)

i got 10.28 but that rounds up to 10.3
