2x+y=9 let x=3 what is y

3

Step-by-step explanation:

Step 1:

2x + y = 9          Equation

Step 2:

2 ( 3 ) + y = 9    Input x

Step 3:

6 + y = 9     Multiply

Step 4:

y = 9 - 6     Subtract 6 on both sides

y = 3

Hope This Helps :)

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d

x equals 1

step-by-step explanation:

f(4)=f(×)

x=1
