How do I solve -3x+y=24 -2x=+18+5y

Mathematics

ExtremeBDS [4]3 years ago
3 0

Answer:

Let's solve by eliminating x. Since 18 is the lowest common multiple , let's multiply the first equation by 3 and the second by -2.

18x−21y=24

−18x+10y=−2

Add the two equations.

−11y=22

Divide by -11 to isolate y.

y=−2

Substitute y=−2 into either of the 2 equations, I'll just use the second one.

9x+10=1

9x=−9

x=−1

Help me please!!!!! I need help with angles
Salsk061 [2.6K]

Answer:

<CFE = 28

<RPQ = 53

Step-by-step explanation:

1)

<CFE + 152 = 180

<CFE = 180 - 152

<CFE = 28

2)

Complementary means the angles add up to 90 so:

<RPQ + 37 = 90

<RPQ = 90 - 37

<RPQ = 53
