Question

solve using substitution method.
2x+7y=39
5x+5y=3​

Answer 1

Step-by-step explanation:

From equation 1 ,we find out the value of x in terms of y.

This value of x will be substituted in the 2nd equation.

Answer 2

Step-by-step explanation:

x=(39-7y)/2 put in 2nd eqn

we get

5(39-7y)/2 +5y=3

5(39-7y)+10y=6

195-35y+10y=6

195-6=25y

y=189/25
