Step-by-step explanation:

please mark brainliest answer.

Answer 2

Answer:

substitute method

x=(136-6y)/4

sub in equation 2

6 (136-6y)/4+5y=164

816-36y/4 +5y=164

4 (204-9y)/4+5y=164

204-9y+5y=164

204-4y=164

-4y=164-204

-4y=-40

4y=40

y=10

sub in equation 1

4x+6 (10)=136

4x+60=136

4x=136 -60

4x=76

x=76/4

x=19
