HELP! PLEASEEEE! WILL FAN + METAL

Solve the system by substitution
3x-4y= -5
x= 2y-3

Answer 1

as you have 3x-4y = -5

here you put 2y-3 in the place of x because x= 2y-3

thus we get to

3(2y-3) -3 =0

now solve for y

Answer 2

put the vale of x in the second equation in the first equation and then solve for y

Answer 3

after that pick any equation put the value of y and then solve for x

Answer 4

3(2y-3) -4y = -5

solve for y

Answer 5

y=7?
