Question

5 x minus 2 is equal to 18

Answer 1

$\mathbb{ELLO \ THERE!}$

--------------------

Pre-Requisite Knowledge

• When in an equation, a number with a +ve sign goes to the other side of the equal symbol, the number becomes -ve.
• EG: 12 + x = 1 when shifting happens, it results to x = 1 - 12
• When in an equation, a number with a -ve sign goes to the other side of the equal symbol, the number becomes +ve.
• EG: -12 + x = 1 when shifting happens, it results to x = 1 + 12
• When in an equation there is a fraction, the denominator goes to other side and multiplies.
• EG: x/12 + 2 = 1, when it shifts happen, it results to x + 2 = 1 × 12
• Then its vice-versa with multiplication

--------------------------

$\mathbb{ANSWER}$

5x - 2 = 18

5x = 18 + 2

5x = 20

x = $\frac{20}{5}$

x = 4

Therefore the required answer is 4
