The first answer is A the second answer is B
Answer:
(1): -4.7 - 2.3x + 0.5 - 4x
(2):-5.3x-4.2-x
(3):-3.4-6.3x-0.8
Step-by-step explanation:
By Collecting like terms and adding the answer I get -6.3x - 4.2
(1):-4.7-2.3x+0.5-4x
Collect like terms
-2.3x-4x-4.7+0.5
-6.3x-4.2
(2):-5.3x-4.2-x
Collect like terms
-5.3x-x-4.2
-6.3x-4.2
(3): -3.4-6.3x-0.8
Collect like terms
-6.3x-3.4-0.8
-6.3x-4.2
x = 5
y = -1
Step-by-step explanation:
from second equation,
by putting the value of y in first equation
- y = -x + 4
- -1 = -x + 4
- -x = -1 -4
- -x = -5
- x = 5
x = 5 and y = -1
<h3>Simplifying
</h3>
5.5 + -1x = -4.5 + -1x
<h3>
Add 'x' to each side of the equation.
</h3>
5.5 + -1x + x = -4.5 + -1x + x
<h3>
Combine like terms: </h3>
-1x + x = 0
5.5 + 0 = -4.5 + -1x + x
5.5 = -4.5 + -1x + x
<h3>
Combine like terms:</h3>
-1x + x = 0
5.5 = -4.5 + 0
5.5 = -4.5
<h3>
Solving:
</h3>
5.5 = -4.5
<h3>
This equation is invalid, the left and right sides are not equal, therefore there is no solution.</h3><h3 />
