x = 200 is NOT a solution to the equation x ÷ 2 - 40 = 10

z = 20 is NOT a solution to the equation 5 × (z - 6) = 30

So?

This problem illustrates grouping like terms and dealing with subtraction in an equation.

Solve x - 12 + 20 = 37.

Replacing the -12 with a +(-12), we get

x + (-12) + 20 = 37.

Since addition is associative, the two like terms (the integers) may be combined.

(12) + 20 = 8

The left side of the equation becomes

2x + 10 + (-10) = 20 + (-10) ==>

2x + (10 + (-10)) = 20 - 10 ==>

2x + 0 = 10 ==>

2x = 10.

The x is multiplied by 2, therefore we divide both sides by 2 to solve for x:

2 × (5 + 1 + 4) = 20 ==>

2 × 10 = 20 ==>

20 = 20 so our solution is correct.

Then:
2x = 10 ==>

2x ÷ 2 = 10 ÷ 2 ==>

(2x)/2 = 5 ==>

x = 5.

Jesus, get it right.

3x + 6y = -6

Divide this equation by 3 and rearrange for x, then use this x in your other equation. You will be able to get a value for y. Then you can finally use this value to get a value for x.

3X+6Y= -6
5X-2Y=14 |*3

So we get

3X+6Y= -6
15x-6Y = 42

Which leads to

18x = 36 | / 18

x = 2
