What is the value of x

barxatty [35]

X = 15

X + 90 = 7x

X = 7x - 90

X - 7x = -90

-6x = 90

Divide both sides by -6

X = 15

Solve 2x^2 − 8x = −7

kenny6666 [7]

Answer:

The answer to your question is below

Step-by-step explanation:

2x² - 8x = - 7

Divide by 2

$\frac{2}{2} x^{2} - \frac{8}{2} x = \frac{-7}{2}$

Complete the trinomial

$x^{2} - 4x + (2)^{2} = \frac{-7}{2} + (2)^{2}$

Simplify

$x^{2} - 4x + (2)^{2} = \frac{- 7 + 4}{2}$

$x^{2} - 4x + 4 = \frac{-3}{2}$

Factor

(x - 2)² = $\frac{-3}{2}$

Get the square root

$\sqrt{(x - 2)^{2}} = \sqrt{\frac{-3}{2}}$

Simplification

x - 2 =± $\sqrt{\frac{3}{2}} i$

x₁ = 2 + $\sqrt{\frac{3}{2}} i$

x₂ = 2 - $\sqrt{\frac{3}{2}}$
