A system of equations is given below:

y = 3x + 4
2x + 3y = 10

Which of the following steps could be used to solve by substitution?

3x+ 4= 2x+3y
2x+ 3(3x+ 4)=10
2(3x+4) + 3y =10
3(y= 3x+4)

y = 3x + 4
2x + 3y = 10

We need to substitute the first equation into the second equation. So, we would substitute y in the second equation with 3x + 4.

2x + 3(3x + 4) = 10

This would be answer choice B. 2x + 3(3x + 4) = 10.
