Question

Y=x+2. Y=3x can someone pls help

Answer 1

(1, 3 )

Explanation:

Given the 2 equations

y = x + 2 → (1)

y = 3x → (2)

Substitute y = 3x into (1)

3x = x + 2 ( subtract x from both sides )

2x = 2 ( divide both sides by 2 )

x = 1

Substitute x = 1 into either of the 2 equations for corresponding value of y

Substituting into (1)

y = 1 + 2 = 3

solution is (1, 3 )

Answer 2

Explanation:

Step 1: Define Systems

y = x + 2

y = 3x

Step 2: Solve for x

Substitution

1. Substitute in y: 3x = x + 2
2. [Subtraction Property of Equality] Subtract x on both sides: 2x = 2
3. [Division Property of Equality] Divide 2 on both sides: x = 1

Step 3: Solve for y

1. Define original equation: y = 3x
2. Substitute in x: y = 3(1)
3. Multiply: y = 3
