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)

see plug the value of y in equation 2
equation y states y = 3x + 4

rishavraj · Answer

tht means substitution of y :)
