Ii dont understand how to solve a system of linear equations using the substitution method

Answers

so 8x-7y=-7
-16+12x=14
you can simplify the sceon equation
-8+6x=7
add 8 to both sides
6x=15
divide by 6
x=15/6
subssitute
8(15/6)-7y=-7
120/6-7y=-7
20-7y=-7
subtract 20
-7y=-27
divide by -7
y=27/7

x=15/6
y=27/7
