Which step should be performed first wehn evaluating 18 minus 3 plus 11 times 2 plus 5

11 times 2

Step-by-step explanation:

parenthesis

exponents

multiplication                    -             multiplication is the first of the list you                                                                      have, so therefore, 11 * 2 comes first

division

addition

subtraction

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3
