Answer
x = 10
Work Step by Step
2.1x +5 -1.6x =10 Simplify 2.1x -1.6x
0.5x +5 =10 Subtract 5 from both sides
0.5x +5-5 =10 -5
0.5x =5 Divide by 0.5 on both sides
$\frac{0.5x}{0.5}$=$\frac{5}{0.5}$
x=$\frac{50}{5}$
x=10
The solution is 10
Check
2,1x +5 -1.6x =10 Replace x with $\frac{1}{10}$
2,1$\times$10 +5 -1.6$\times$10 =10
21+5 -16=10
26-5=10
10=10
