4(x+x+7)-2x+8-4
Substitute x with 1
4(1+1+7)-2(1)+8-4
=4(2+7)-2+4
=4(9)-2+4
=36-2+4
=34+4
=38
4(x+x+7)-2x+8-4
Substitute x with 2
4(2+2+7)-2(2)+8-4
=4(4+7)-4+4
=4(11)
=44. Hope it help!
Answer:
Sorry but I really don’t know
Step-by-step explanation:
Answer:
Simplify \frac{2}{3}x
3
2
x to \frac{2x}{3}
3
2x
.
x=\frac{2x}{3}-4x=
3
2x
−4
2 Multiply both sides by 33.
3x=2x-123x=2x−12
3 Subtract 2x2x from both sides.
3x-2x=-123x−2x=−12
4 Simplify 3x-2x3x−2x to xx.
x=-12x=−12
