Step 1- Solve for the value of x

2x = 60

x = 30

Step 2- Plug in 30 for x in the second equation

Find the measure of an angle such that the difference between its supplement and 3 times its complement is 46°.

artcher [175]

supplement means the sum of the two angles is 180° → y = 180 - x

complement means the sum of the two angles is 90° → y = 90 - x

supplement - 3(complement) = 46

(180 - x) - 3(90 - x) = 46

(180 - x) - 270 + 3x = 46

2x - 90 = 46

2x = 136

x = 68

Answer: 68°

The ravens won three more games than they lost.they played 96 games.how much games did they win?

balandron [24]

$x-the \ number \ of \ games \ won \ \\\\ y-the \ number \ of \ games \ lost \\\\ x= y+3 \\\\ x+y=96 \\\\ 3+y+y=96 \\\\ 3+2y=96 \\\\2y=96-3\\\\2y=93 \\\\ \boxed{y=\frac{93}{2}=46.5\approx46\ games \ lost} \\\\ x=3+46 \\\\ \boxed{x=49 \ games \ win}$
