Question

Find the value of m if 5m divided 5-3 =55

Answer 1

5m÷5-3=55
5m÷2=55
5m=110
m=110÷5
m=22

Answer 2

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.

Answer

$\frac{5m}{5 - 3}$ = 55

$\frac{5m}{2}$ = 55

5m = 55 × 2

5m =  110

 m = $\frac{110}{5}$

 m = 22
