Question

What is the solution of the equation 3(x+2)=x+11

Answer 1

$3(x + 2) = x + 11 \\ 3x + 6 = x + 11 \\ 2x = 5 \\ x = \frac{5}{2} = 2.5$

Answer 2

Answer:

x=3 and y=4

Step-by-step explanation:

I will try to solve your system of equations.

x+y=7;x+2y=11

Step: Solvex+y=7for x:

x+y+−y=7+−y(Add -y to both sides)

x=−y+7

Step: Substitute−y+7forxinx+2y=11:

x+2y=11

−y+7+2y=11

y+7=11(Simplify both sides of the equation)

y+7+−7=11+−7(Add -7 to both sides)

y=4

Step: Substitute4foryinx=−y+7:

x=−y+7

x=−4+7

x=3(Simplify both sides of the equation)

Answer:

x=3 and y=4
