Question

Drag the tiles to the correct boxes to complete the pairs. Not all tiles will be used. Solve the equations for x and match the solutions.

Answer 1

Answer:

$-ax - 20 = -14$ => $x = -\frac{6}{a}$

$4 = \frac{6}{a}x + 5$ => $x = -\frac{a}{6}$

$7 + 2ax = 13$ => $x = \frac{3}{a}$

Step-by-step explanation:

$-ax - 20 = -14$

$-ax - 20 + 20 = -14 + 20$

$-ax = 6$

$\frac{-ax}{-a} = \frac{6}{-a}$

$x = -\frac{6}{a}$

$4 = \frac{6}{a}x + 5$

$4 - 5 = \frac{6}{a}x + 5 - 5$

$- 1 = \frac{6}{a}x$

$- 1*\frac{a}{6} = \frac{6}{a}x*\frac{a}{6}$

$-\frac{a}{6} = x$

$x = -\frac{a}{6}$

$7 + 2ax = 13$

$7 + 2ax - 7 = 13 - 7$

$2ax = 6$

$\frac{2ax}{2a} = \frac{6}{2a}$

$x = \frac{3}{a}$
