Can someone just help me with this simultaneous equations with substitution. I’ve asked ten times and no one has helped. Please

Step-by-step explanation:

3x + 4y = 11 ----------------------(1)

x = 15 - 7y   ----------------------(2)

Put Eq. (2) in (1)

3(15 - 7y) + 4y = 11

45 - 21y + 4y = 11

45 - 17y = 11

Subtracting 45 to bot sides

-17y = 11 - 45

-17y = -34

Dividing both sides by -17

y = -34 / -17

y = 2

Put y = 2 in Eq. (2)

x = 15 - 7(2)

x = 15 - 14

x = 1

Solution Set = {x,y} = {1,2}

Hope this helped!
