Answer:

y = 3

Step-by-step explanation:

substitute the x in 2x - y = 7 by x = 3y - 4 and then solve

2(3y - 4) - y = 7

Distribute the 2 into the parenthesis

6y - 8 -y = 7

combine like terms

5y - 8 = 7

add 8 on both sides

5y = 15

divide by 5 on both sides to isolate the y-value

y = 3

Answer:

score = 63

Step-by-step explanation:

1. To write the proportion take the score of the test over the number of points and set it equal to the percent over 100

score 90

----------- = -----------

70 100

Using cross products

100 * score = 90*70

100 score = 6300

Divide by 100

100/100 * score = 6300/100

score = 63
