Question

select all the equations where $y = 10$ is a solution. choose 2 answers: a $y + 11 = 22$ b $8 = 18 - y$ c $60 = 6y$ d $\frac{y}{5} = 4$ e $10y = 20$

Explanation:

for Option A:

Step1: Substitute \( y = 10 \) into \( y + 11 = 22 \)

Left - hand side (LHS): \( 10+11 = 21
eq22 \) (Right - hand side, RHS). So \( y = 10 \) is not a solution for option A.

for Option B:

Step1: Substitute \( y = 10 \) into \( 8=18 - y \)

Right - hand side (RHS): \( 18 - 10=8 \), which is equal to the left - hand side (LHS = 8). So \( y = 10 \) is a solution for option B.

for Option C:

Step1: Substitute \( y = 10 \) into \( 60 = 6y \)

Right - hand side (RHS): \( 6\times10 = 60 \), which is equal to the left - hand side (LHS = 60). So \( y = 10 \) is a solution for option C.

for Option D:

Step1: Substitute \( y = 10 \) into \( \frac{y}{5}=4 \)

Left - hand side (LHS): \( \frac{10}{5}=2
eq4 \) (RHS). So \( y = 10 \) is not a solution for option D.

Answer:

B. \( 8 = 18 - y \)
C. \( 60 = 6y \)
