Given the square below, solve for x. x = 6 x = −2 x = −6 x = 2

Since this is a square, its sides must be congruent. This means you can set the given values equal to each other to solve for x.

x + 7 = 4x - 11

Subtract 7 from both sides.

x = 4x - 18

Subtract 4x from both sides.

-3x = -18

Divide both sides by -3.

x = 6

x = 6

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
