Question

Rick out the solution from the values in the given bracket next to each equation.
a) x + 7 = 12 (2,7,9,3,5)
b) y - 1 = 9 (12,11,10)
c) 10x = 90 (7,8,9)

Answer 1

$\huge \bigstar {\tt \red{Answer}} \huge \bigstar$

a ) x + 7 =12

x = 12 -7

x = 5

b) y -1 =9

y = 9 + 1

y =10

c) 10 x =90

x = 90 /10

x = 9
