Question

2. Solve the system using substitution. (1 point)

2x+2y=38
y=x+3
(8.11)
(4.7)
35 47
4²4
(-4.-7)

Answer 1

It’s (8,11) if you sub everything

Answer 2

(8, 11 )

Explanation:

Given the 2 equations

2x + 2y = 38 → (1)

y = x + 3 → (2)

Substitute y = x + 3 into (1)

2x + 2(x + 3) = 38 ← distribute and simplify left side

2x + 2x + 6 = 38

4x + 6 = 38 ( subtract 6 from both sides )

4x = 32 ( divide both sides by 4 )

x = 8

Substitute x = 8 into (2) for corresponding value of y

y = 8 + 3 = 11

Solution is (8, 11 )
