Solve y - 2x = 3 and Y = 3x + 5 by substitution

x = -2

Step-by-step explanation:

y - 2x = 3, y = 3x + 5

Substitute the value of y for y

3x + 5 - 2x = 3

Step 1: Simplify both sides of the equation

3x + 5 − 2x = 3

3x + 5 + −2x = 3

(3x + −2x) + (5) = 3 (Combine Like Terms)

x + 5 = 3

x + 5 = 3

Step 2: Subtract 5 from both sides

x + 5 − 5 = 3 − 5

x = −2

its a website that gives you all the answers im being dead serious

1/4 and 8/3 because:

the reciprocal if 4 is 1/4 because 4 is used as 4/1 and the opposite of that is 1/4. the opposite of 3/8 is 8/3 so that is the answer.

after simplifying it i got: -36.25 as my answer. hope that !
