Answer:
−2(−9x+5)−4x=2(x−5)−4
Step 1: Simplify both sides of the equation.
−2(−9x+5)−4x=2(x−5)−4
(−2)(−9x)+(−2)(5)+−4x=(2)(x)+(2)(−5)+−4(Distribute)
18x+−10+−4x=2x+−10+−4
(18x+−4x)+(−10)=(2x)+(−10+−4)(Combine Like Terms)
14x+−10=2x+−14
14x−10=2x−14
Step 2: Subtract 2x from both sides.
14x−10−2x=2x−14−2x
12x−10=−14
Step 3: Add 10 to both sides.
12x−10+10=−14+10
12x=−4
Step 4: Divide both sides by 12.
12x
12

Answer:
See below ~
Step-by-step explanation:
<u>Finding x-intercept</u>
- Take y = 0
- 2x - 5(0) = 10
- 2x = 10
- x = 5
- x-intercept is at (5, 0)
<u>Finding y-intercept</u>
- Take x = 0
- 2(0) - 5y = 10
- -5y = 10
- y = -2
- y-intercept is at (0, -2)
<u>Graph (with points marked)</u>
