Select all the equations that have 9 as a solution.
j + 8 = 72
m × 3 = 27
b + 4 = 13
p – 5 = 4
q ÷ 3 = 27

Answer:

m x 3 = 27

p - 5 = 4

b + 4 = 13

The equation with solution 9 is

m × 3 = 27,

b + 4 = 13

and p – 5 = 4.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

1. j + 8 = 72

j= 72- 8

j= 64

2. m × 3 = 27

m= 37/3

m=9

3. b + 4 = 13

b= 13- 4

b = 9

4. p – 5 = 4

p= 9

6.q ÷ 3 = 27

q= 27 x 3

q= 81

Hence, the equation with solution 9 is m × 3 = 27, b + 4 = 13 and p – 5 = 4.
