Arnold needs to simplify the expression below.
4.3x3+ 11
(8.2-0.5x 7)-6
which operation should he perform first?
7+6
0.5x7
8.2-0.5
3+11

Solve the following inequalities and show the solution on a number line. 2x+3< 3(4x+5)

Can someone explain to me how to do

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.
