What is the solution to the set of equations? Y=1/3x-10 2x+y=4

Sagot :

Answer:

x=120/7

Step-by-step explanation:

Y=1/3x-10  , 2x+y=4

2x+1/3x-10=4

[tex]\frac{2*3x+1*1x}{3*1}[/tex]-10=4

[tex]\frac{6x+1x}{3}-10=4[/tex]

7x/3-10=4

7x/3-10+10=4+10

7x/3=40

[tex]\frac{7}{3}x*\frac{3}{7}=40*\frac{3}{7}[/tex]

x=120/7
