Answer:
(4, 2)
Step-by-step explanation:
Start by combining the equations
2x + 2x = 4X
4y - 4y = 0
16 + 0 = 16
4x = 16
x = 4
Now that you have one variable plug it back in to one of the original equations
2(4) + 4y = 16
8 + 4y = 16
4y = 8
y = 2
(4, 2)
Answer:
x = 22/15
Step-by-step explanation:
17x - 6 + 3x - 5 = x + 11 + 4x
Combine like terms on each side.
20x - 11 = 5x + 11
Add 11 to both sides. Subtract 5x from both sides.
15x = 22
Divide both sides by 15.
x = 22/15
Answer:5
Step-by-step explanation: remeber pemdas
first we do parenthesies(I have bad spelling)
17+6/3-7*2
then we do multiplication and divition, it matters what comes first
17+2-7*2
17+2-14
5
Sorry I can't solve it.
Firstly, the equation is wrong. It is supposed to be <span>81 ≠ </span><span>30.25
Second of all, this is the best I got </span>81= <span><span>−<span>76 <span>(<span>cos<span>(r) </span></span></span></span></span>+ <span>106.25</span></span>
