Question

I need help pleasee

Answer 1

Answer:

2x+3=-13

x=5

Step-by-step explanation:

it says 2 times a number which would be the 2x, and it says the sum of that and 3 which would be 2x+3 and it says is 13. 2x+3=13

now solving it

2x+3=13

subtract 3 from both sides

2x=10

and divide 2 from both sides

x=5

Answer 2

Answer:

Equation: 2n+3 = -13 Number: -8

Step-by-step explanation:

Ok so, it states the sum of twice a number and 3 equals -13. The question states to consider the number as "n" so the equation is 2n + 3 = -13.

Subtract 3 on both sides. Now . you have 2n = -16.

Divide 2 on both sides.

n = -8
