Sam solved the equation -7x+4=-59 and his answer is X=9 

Do Sam's check. Is his answer correct?

-7(9)+4=-59

-63+4=-59

-59=-59

Yes, Sam's answer is correct

Subtract 9 from the product of 4 and x. The result is 11. Write the equation.

4x-9=11

Solve for X

3x+9y=15

3x+9y=15

3x=15-9y

x=5-3y

500

Solve for X

-35=10y+5x

-34=-10y+5x

10y-35=5x

2y-7=x

Math 3

Solve this equation and determine how many solutions there will be.

12(2x+3)=4(6x+9)

12(2x+3)=4(6x+9)

24x+36=24x+36

36=36

Since 36 does equal 36 then we know there are an infinite number of solutions for this equation. Any number will make this true.

Mr. James buys a car with a down payment of 3,200 and pays $350 per month. If the car costs $15,800, how many months will it take pay off the car?

Let X=number of months

3200+350x=15,800

350x=12,600

Sandy is thinking of a number is she multiplies her number by -8 and then subtracts 26, the result is 126. What is Sandy's number?

Let x=the number

-8x-26=126

-8x=152

x=-19

Sandy's number is -19
