Question

What is the value of y in the solution to the following system of linear equations?

2x+2=y
2y=5x-1

Answer=12

Answer 1

U kinda answered but yeah 12 lol

Answer 2

Explanation:

we are given these two equations and we need to solve for y

2x+2=y

2y=5x-1

lets use the substitution method to eliminate one of the variable first

using the first equation y=2x+2 and substituting in the second equation we get

2(2x+2)= 5x -1

distribute the 2 on parenthesis

4x+4 =5x -1

Bring all the like terms to one side

4+1 =5x-4x

5= x

so we get x=5 .

Now to get y we can plug this value of x in the first equation

y=2x+2

so we get

y=2(5)+2

y=10+2

y=12
