To solve for x, we can start by simplifying the equation.
0.72 = 0.4(x + 1.4)
Distribute the 0.4:
0.72 = 0.4x + 0.56
Subtract 0.56 from both sides:
0.72 - 0.56 = 0.4x
0.16 = 0.4x
Now divide both sides by 0.4:
0.16/0.4 = x
0.4 is the same as 4/10, so:
0.16/(4/10) = x
Multiply the numerator and denominator of the fraction by 10:
0.16*10/(4*10) = x
1.6/4 = x
Simplify the fraction:
0.4 = x
So the solution is x = 0.4.
Solve for x.
0.72=0.4(x+1.4)
