Question

Solve the system of equations using substitution

2x+2y=38
y=x+7

Answer 1

solve the system of equations using substitution

2x+2y=38

y=x+7

Answer:

x= 6, y= 13

Answer 2

x = 6 and y = 13

Explanation:

2x + 2y = 38 ⇒ eq 1

y = x + 7 ⇒ eq 2

Substituting the value of y from eq 2 in 1:

2x + 2(x + 7) = 38

2x + 2x + 14 = 38

4x = 24

x = 24/4

x = 6

Now substituting the value of x in eq 2:

y = ( 6 ) + 7

y = 13
