Astudent is solving the equation 2x - 1 = 16x + 2
step 1: 2x - 1 = 16x + 2
step 2: 2x - 1 = (24)x + 2
step 3: 2x - 1 = 24x + 8
which is the next step?
a. 2(x - 1) = 4(x + 2)
b. x - 1 = 4x + 8
c. x - 1 = x + 2
d. x -1 = -(4x + 8)

Express the following as a function of a single angle. cos(60) cos(-20) - sin(60) sin(-20)

Arrange the steps to solve this system of linear equations in the correct sequence. x + y = -2 2x – 3y = -9 tiles subtract 3x + 3y = -6 (obtained in step 1) from 2x – 3y = -9 (given) to solve for x. substitute the value of x in the first equation (x + y = -2) to get y = 1. the solution for the system of equations is (-3, 1). x = -15 the solution for the system of equations is (-15, 13). add 3x + 3y = -6 (obtained in step 1) to 2x – 3y = -9 (given), and solve for x. x = -3 substitute the value of x in the first equation (x + y = -2) to get y = 13. multiply the first equation by 3: 3(x + y) = 3(-2) 3x + 3y = -6.

Me i'm timed right now! there's 4 answer
