Q19Multiple choice
The sum of two numbers is 60 and their difference is 30.
- (a)If smaller number is x, the other number is .(use sum)
- (b)The difference of numbers in term of x is .
- (c)The equation formed is .
- (d)The solution of the equation is . (e) The numbers are and . Words Numbers Algebra Multiply both sides of 2×3=6 x = y implies an equation by the same non-zero number, and 4×2×3=4×6 zx = zy (z ≠ 0) the statement will still be true. 8 × 3 = 24
