"twice of a number increased by seventeen is 8.”

Hey!

Solution:

twice of a number is 2n.

increased by seventeen is + 17

is eight = 8

2n + 17 = 8

Hope This Helped! Good Luck!

x = -4.5 (-4 and 1/2) (-5/2)

Step-by-step explanation:

twice of a number: 2x

increased by seventeen: +17

is 8: = 8

2x + 17 = 8

-17          -17

2x = -9

2       2

x = -4.5 (-4 and 1/2) (-5/2)

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
