Answer:y=21/5, x=7/10

Step-by-step explanation:Substitute y=6x

4x=6x=7

Simplify 4x+6x

10x=7

isolate x for 10x=7:

10x=7

Divide both sides by 10:

10x/10=7/10

Simplify:

x=7/10

For y=6x substitute x=7/10

y=6*7/10

Convert element to fraction:

6/1*7/10

Cross- cancel common factor:2

3/1*7/5

Multiply fractions:

3*7/1*5

Multiply the numbers:3*7=21

=21/5

y=21/5

The solutions to the systems of equations are:

y=21/5,x=7/10
