Question

2x + 8y = 20
y = 3

Can someone tell me the answer to this pls I beg you

Answer 1

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

Answer 2

x=-2

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
