Question

15. If written in standard form, what are the values of A, B, and C in the equation 2x = 4(-y + 5)?
A. A= 2, B= -4, C= 5
B. A= 2, B= -4, C= 20
C. A= 2, B= 4, C= 5
D. A= 2, B= 4, C= 20​

Answer 1

Answer:

B

Step-by-step explanation:

First solve RHS

RHS= 4(-y+5)

Multiply 4 with -y and 5 individually

4×(-y) + 4× 5

:. -4y+20

Hence, 2x= -4y+20

2x+4y-20=0 (found by shifting RHS to LHS and forming an equation)

a=2, b=-4, c= 20 {Hence, Option B}

Answer 2

Answer:

15. If written in standard form, what are the values of A, B, and C in the equation 2x = 4(-y + 5)?

A. A= 2, B= -4, C= 5

B. A= 2, B= -4, C= 20

C. A= 2, B= 4, C= 5

D. A= 2, B= 4, C= 20

→B. A= 2, B= -4, C= 20
