Question

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

Answer 1

Answer:

x=120/7

Step-by-step explanation:

Y=1/3x-10  , 2x+y=4

2x+1/3x-10=4

$\frac{2*3x+1*1x}{3*1}$-10=4

$\frac{6x+1x}{3}-10=4$

7x/3-10=4

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

7x/3=40

$\frac{7}{3}x*\frac{3}{7}=40*\frac{3}{7}$

x=120/7
