solve 3 - 7(4x - 4) = -4x + 115 — step-by-step solution

Let's solve in

ℝ

3 - 7 \cdot (4 x - 4) = - 4 x + 115

3 - (28 x - 28) = - 4 x + 115

3 - 28 x + 28 = - 4 x + 115

31 - 28 x = - 4 x + 115

- 28 x + 4 x = 115 - 31

- 24 x = 84

x = \frac{84}{-24}

x = - \frac{84}{24}

By dividing the numerator and the denominator by

12

, this fraction:

\frac{84}{24}

can be rewritten as fraction:

\frac{7}{2}

Solution obtained:

x = - \frac{7}{2}

The numeric value of:

x = - \frac{7}{2}

is:

x = -3.5

▷Result: $x = - \frac{7}{2}$

▷▷Numeric result:

x = -3.5
