Answer:

x = 10

Step-by-step explanation:

$x - 7 = 13 - x$

Step 1 : Collect like terms and simplify

$x + x = 13 + 7 \\ 2x = 20$

Step 2 : Divide both sides of the equation by 2

$\frac{2x}{2} = \frac{20}{2}$

Step 3 : Simplify by cross cancellation of common term : 2

$x = 10$

Juliette [100K]

Answer:

see bottom

Step-by-step explanation:

divide through by 4

x2 - 2x - 3 = 0

x2 - 3x + x - 3 = 0

(x2 - 3x) + (x - 3) = 0

x(x - 3) + 1(x - 3) = 0

(x + 1) (x - 3) = 0

x + 1 = 0 and x - 3 = 0

x = -1 and x = 3
