Mathematics

Leni [432]2 years ago

Answer:

x = 1

Step-by-step explanation:

<u>Step 1:  Choose one of the equations to solve for y:</u>

x - y + 1 = 0

(-y) / -1 = (-1 - x) / -1

y = 1 + x

<u>Step 2:  Plug in y into either equation</u>

3x + 2(1 + x) = 7

3x + 2 + 2x - 2= 7 - 2

5x / 5 = 5 / 5

x = 1

Answer:  x = 1

(WILL GIVE BRAINLIEST) Solve for x.
Oksanka [162]

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

=

−4

12

x= -1/3
