Write an equation for the number of points, y Enrique scores on the test when he answers x questions correctly.

kramer

Answer:
1. 3x = y
2. 7x= y.

Explanation:
If x is the amount of points each question that is answered correctly received then the coefficient that x is multiplied by will be the amount for each test.

For the first equation we have 3 as the amount answered correctly time x the points each one is worth = total points y.

For the second equation we have 7 as the amount answered correctly time x the points each one is worth = total points y .

Solve for x and y 2x+7=3y-1

zlopas [31]

To solve for x and y, isolate each variable and simplify your equation:

Solve for x:
2x+7=3y-1 (Subtract 7 on each side)
2x=3y-8 (Divide by 2 on each side)
x= $\frac{3y}{2} -4$

Solve for y:
2x+7=3y-1
2x+8=3y (Add 1 on each side)
$\frac{2x}{3} + \frac{8}{3}$ =y (Divide by 3)
y= $\frac{2x}{3} + \frac{8}{3}$

~I hope this helps!~
