Hi Nunya,

x+(2×8)-2=4

In this case we will solve for x. Due to order of operations we will begin by multiplying the numbers in the parentheses.

x+(16)-2=4

x+16-2=4

x+14=4

-14 -14

x= -10

In this equation, x is the variable, which essentially means that its a placeholder for a number. When there is only one variable in an equation, you can typically solve to find its value.

To solve for x, you will want x alone on one side of the equation. Start by using PEMDAS (Parentheses, Exponents, Multiplication/Division, Addition/Subtraction) to combine the numbers. So, start in the parentheses and multiply those 2 numbers.

x + (16) -2 = 4

Then, complete the subtraction on the left side of the equation.

x + 14 = 4

Subtract 14 from both sides of the equation to get x alone. I'm showing intermediate steps here. If you need, I would recommend writing the subtraction from both sides directly under the values you're subtracting it from, like shown below.

x + 14 = 4

-14 -14

x + 0 = - 10

x = -10

You can then plug this value for x back into the original equation to check that its the right answer and that there were no math errors.

(-10) + (2*8) - 2 = 4

-10 + 16 - 2 = 4

6 - 2 = 4

4 = 4

Since 4 = 4 is a true statement, the x value is correct.

x + (2x8) - 2 = 4

x + (2x8) = 4 + 2 = 6

x = 6 - (2x8) = 6 - 16 = - 10
