Question

Solve the following system of equations.

3x + 2y - 5 = 0
x = y + 10

Answer 1

put x=y+10 into 1st equation...

Answer 2

given x=y+10
so in another equation if we replace the value of x we get
3(y+10)+2y-5=0
=>3y+30+2y-5=0
=>5y+25=0
=>5y=-25
=>y=-5
now in another equation we are gonna replace the value of y
x=-5+10
=>x=5
