İS 5

x=6

Step-by-step explanation:

2x-7=5

2x=12

x=6

In explanation.

Step-by-step explanation:

Let "a number" be represented by n.

"twice a number" →2n.

"twice a number and k" →2n+k.

"7 less than twice a number and k" →(2h+k)−7.

2x=12

x=12/2

x=6

Simplified form.

2x-7=5

2x=12

x=6

Hope this helps.

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
