4x - 5y = -15
y = -3x + 22
Plug in your y= equation into the y variable in the other equation
4x - 5 (y) = -15
^^
y = (-3x + 22) = -15
4x - 5 (-3x + 22) = -15
Distribute
4x + 15x - 110 = -15
Combine like terms and add 110 over to -15
19x = 95
Then, divide the whole equation by 19
x = 5
Then, plug in your x into your y= equation
y = -3 (5) + 22
y = -15 + 22
y = 7
<em><u>x = 5</u></em>
<em><u>y = 7</u></em>
<em><u>(5, 7)</u></em>
Answer:
x ∈ R (all reals)
Step-by-step explanation:
14 - (2x + 5) = -2x + 9
Take out parentheses
14 - 2x - 5 = -2x + 9
Simplify
9 = 9
<em>Since 9 does equal 9, it means that this equation can be true for all real values of x.</em>
Answer:
-1, 1
Step-by-step explanation:
what is 1/3 of -3 and 3
Answer:
2 step proof, Subtraction Property
Step-by-step explanation:
This one is pretty easy if you know a shortcut. Addition, Subtraction, Multiplication, and division properties.
Think about it this way. Subtract angle 1 from QUS. Then subtract angle 2 from RUT. Knowing RUT is equal to QUS means that the differences are the same.
Don't know if this is right or not but hope this helps.
