Answer:
x=-2
Step-by-step explanation:
y=3 so 8y=24 sooooooo 2x+24=20 if you subtract 24 from both sides you get 2x=-4 divide by 2 on both side and you get x=-2
Answer:
2x+8y=20
Substitute Y
2x+8(3)=20
Multiply 8 * 3
2x+ 24= 20
substract 24 from 20 do it to the other side as well were basically doing inverse operation in order to keep the varieble by itself
2x=-4
Then do inverse operation of multiplication which is division
2x= -4
---- ----
2 2
2x will cross out and x will be left, -4/ 2 equals -2
so x= -2
The answer will be (-2, 3) or if you're just solving for x its going to be -2
