Question

solve 2m -7 n = 7; 3m + n = 22​

Answer 1

Answer:

m=7 and n=1

Step-by-step explanation:

Equation 1 - 2m -7n=7 and

Equation 2 - 3m +n =22

Multiplying with 7 to equation 2

2m-7n=7

21m+7n=154

when we solve it the remaining equation is 23m=161

m=161÷23

m=7

putting the value of m in equation 1

2×7-7n=7

14-7n=7

-7n =7-14

-7n =-7

n =7÷7

n=1
