Answer:
x as a fraction 7[tex]\frac{1}{2}[/tex]
x as a decimal: 7.5
Step-by-step explanation:
2.5x - 6.4 + 1.2x = 21.35
Combine 2.5x and 1.2x to get 3.7x.
3.7x - 6.4 = 21.35
Add 6.4 to both sides.
3.7x = 21.35 + 6.4
Add 21.35 and 6.4 to get 27.75.
3.7x = 27.75
Divide both sides by 3.7.
x = [tex]\frac{27.75}{3.7}[/tex]
Expand [tex]\frac{27.75}{3.7}[/tex] by multiplying both numerator and the denominator by 100.
x = [tex]\frac{2775}{370}[/tex]
Reduce the fraction [tex]\frac{2775}{370}[/tex] to lowest terms by extracting and canceling out 185.
x = [tex]\frac{15}{2}[/tex]
simplify
7[tex]\frac{1}{2}[/tex]
