If 5x - 7 = 10, what is the value of 5/8x - 2?

Answer 1

Hi Dayn W

Solve for x in 5x - 7 =10

Then substitute that value in (5/8)x - 2

Give it a try

Answer 2

First solve 5x - 7 = 10

5x - 7 = 10 (Equation)

5x = 17 (+7 each side)

x = 17/5 (Fraction-form)

Then plug-in 17/5 to next equation: 5/8x - 2

5/8x - 2 (Equation)

5/8(17/5) -2 (Plug-in x)

85/40 -2 (Multiply across fractions)

2.125 -2 (Decimal form)

0.125 or 125/1000 (1/8 simplified) in fraction-form
