The equation describes a linear relationship between x and y. It can be graphed as a straight line. There is nothing to solve until you assign a value to one of the variables, or require they satisfy some additional constraint.

If you want to express it as "y =", then divide by the coefficient of y.
.. y = (-6/5)x -3
.. y = -1.2x -3 . . . . . . in decimal form

In a right triangle abc, cd is an altitude, such that ad=bc. Find ac, if ab=3 cm, and cd= square root 2 cm.

ΔACB ΔCDA

AC² + BC² = AB² AD² + CD² = AC²

BC² = AB² - AC² BC² + CD² = AC² (AD=BC is given)

BC² = AC² - CD²

AB² - AC² = AC² - CD² (both sides were = to BC²)

AB² + CD² = 2AC²

(3)² + (√2)² = 2AC² (AB=3 and CD=√2 were given)

9 + 2 = 2AC²

11 = 2AC²

$\frac{11}{2}$ = AC²

$\sqrt{\frac{11}{2} }$ = AC

$\frac{11\sqrt{2} }{2}$ = AC

Answer:

some do not have numbers so I tried to make the linking as easy to understand as possible, with answers in bold.

Step-by-step explanation:

(6x + 6) + (-3 - 4x) = 2x + 3

4) = 12x - 2

(6p + 4) + (-5p + 8) = p + 12

6) = -n + 5

(-8r + 8) + (-7 - 7r) = -15r + 1

8) = 6r - 13

(1 - 6x) + (7x + 3) = x + 4

10) = -12x - 3
