Answer:
0.8=x
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.
Subtract 7.2 from both sides of the equation to isolate 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
