Olivia wrote the following steps to solve a pair of equations: Step 1: y = −x − 3
y = 4x + 4

Step 2: 4y = −4x −12
y = 4x + 4
Which of the following shows the correct next step to solve the equations by eliminating x? (1 point)

a.5y = −3
b. 5y = −16
c. 5y = −48
d.5y = −8

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
