3.50x + 5.50x + 6 = 51
# 10
9x + 6 = 51
Subtract 6 from both sides
9x = 45
Divide both sides by 9
x = 5

#11
5x - 18 - 4x = -36
x -18 = -36
Add 18 to both sides
x = - 18

Help plssssssssssssssssssssss
Ilia_Sergeevich [38]

Answer:

Then the solution is (4, 6).

Step-by-step explanation:

Let's use the substitution method:

First multiply the second equation by 4, obtaining 4y = -2x + 32.

Now substitute (-2x + 32) for 4y in the first equation:

3x + (-2x + 32) = 36, or

3x - 2x + 32 = 36. or

x = 4.

If x = 4, then the second equation yields y = (-1/2)(4) + 8, or

y = -2 + 8, or y = 6

Then the solution is (4, 6).

Check, using the first equation:

Does 3(4) + 4(6) = 36?  Does 12 + 24 = 36?  YES
