Answer: roughly 4.2593
Step-by-step explanation:
920/216
put the equation through a calculator
approx. 4.2593
<u>A. X=0 Y=5</u>
Those 2 equations are a system. You answer is the value of x and y.
13x+3y=15
y=5-4x
First, lets make each equation fit into y=mx+b
13x +3y=15 y=5-4x
-13x -13x y=-4x+5
3y= -13x +15
Let's use the elimination method to solve this.
y= -4x+ 5 multiply top by 3
3y=-13x+15
3y=-12x+15
3y=-13x+15 subtract the equations
<u>0=x</u>
Lets use the x we just found to solve for y.
y=4x+5
y=4(0)+5
<u>y=5</u>
