Answer:
0.8=x
Step-by-step explanation:
4x+8=7.2+5x
Subtract 4x from both sides of the equation. This eliminates 4x from one side of the equation and leaves the other side with just 1x or x.
- 8=7.2+x
Subtract 7.2 from both sides of the equation to isolate x.
- 0.8=x
So this concludes that 0.8=x
To check your answer, substitute 0.8 into x.
- 4(0.8)+8=7.2+5(0.8)
- 3.2+8=7.2+4
- 11.2=11.2
