What is the solution of the system defined by y=-x+ 5 and 5x + 2y= 147

Sagot :

Answer:

So the solution to the system of equations is the point:

(4/3, 11/3)

Step-by-step explanation:

y=-x+5

5x+2y=14, using y from above in this equation gives you:

5x+2(-x+5)=14  perform indicated multiplication

5x-2x+10=14   combine like terms on left side

3x+10=14 subtract 10 from both sides

3x=4  divide both sides by 3

x=4/3, making y=-x+5 become:

y=-4/3+5

y=-4/3+15/3

y=11/3
