Question

Y=2x+10 y=x+1 solve using substitution

Answer 1

Answer:

x = -9

y = -8

Step-by-step explanation:

here's the solution :-

=》y = 2x + 10

=》y = x + 1

plunging the value of y from equation 1 into equation 2

=》2x + 10 = x + 1

=》2x - x = 1 - 10

=》x = -9

value of x = -9

now, plugging the value of x in equation 2, we get :-

=》y = x + 1

=》y = -9 + 1

=》y = -8
