Work out the value of the expression 2n + 1 when n= -5.

11

Step-by-step explanation:

2 times 5 +1=11

2n+1=-5

2n=-5-1

2n=-6

n=-6÷2

n=-3

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
