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
