Solve 4(5x-7)2-40=-32

Evaluate

4 (5 x - 7) \times 2 - 40 = - 32

Multiply the terms

8 (5 x - 7) - 40 = - 32

Move the expression to the left side

8 (5 x - 7) - 40 - (- 32) = 0

Subtract the numbers

More Steps

8 (5 x - 7) - 8 = 0

Calculate

More Steps

40 x - 64 = 0

Move the constant to the right-hand side and change its sign

40 x = 0 + 64

Removing 0 doesn't change the value,so remove it from the expression

40 x = 64

Divide both sides

\frac{40 x}{40} = \frac{64}{40}

Divide the numbers

x = \frac{64}{40}

Solution

x = \frac{8}{5}

Alternative Form

x = 1.6
