Leonardo wrote an equation that has an infinite number of solutions. one of the terms in leonardo’s equation is missing, as shown below.

3x

Step-by-step explanation:

-(x-1) +5 = 2(x+3) - c

C is the unknown term

Distribute the negative sign and the 2

-x+1 +5 = 2x+6 -c

Combine like terms

-x+6 = 2x +6-c

Solve for c

Add x to each side

-x+x +6 = 2x+x +6-c

6 = 3x+6 -c

Add c to each side

6+c = 3x +6 -c+c

c+6 = 3x+6

Subtract 6 from each side

c+6-6 = 3x+6-6

c = 3x

When c = 3x, the two sides of the equation are equal, and the solutions are infinite.

Step-by-step explanation:

Let be "z" the missing term:

For the system to have infinite number of solutions, must be equal to .

Now you must solve for "z". Apply Distributive property:

Add the like terms on the left side:

Now you need to subtract and 6 from both sides of the equation and finally you can multiply both sides by -1. Then:

$450

step-by-step explanation:

first, you have to multiply 150x2=300

next, you have to add 150+300= 450
