Question

Select all the equations that have g=5 as the solution.

Select all that apply.
A. g + 4 = 15
B. g - 1 = 15
C. 40 + g = 50
D. g - 3 = 2

Answer 1

Equation D

Explanation:

We'll place 5 as g in all equations to test it.

A. LHS: g + 4

(5) + 4

=9

RHS: 15

Hence, equation A can not be certified.

B. LHS: g - 1

(5) - 1

=4

RHS: 15

Hence, equation B can not be certified

C. LHS: 40 + g

40 + (5)

=45

RHS: 50

Hence, equation C can not be certified

D. LHS: g - 3

(5) - 3

=2

RHS:2

Hence, equation D can be certified.
