Answer:
y = 3
x =7
Step-by-step explanation:
to solve this system of equations using substitution method we say, let
5x + 4y = -22
.................... equation 1
2x – 3y = 5...................... equation 2
from equation 2
2x - 3y = 5
2x = 5 + 3y
divide both sides by 2
we have;
2x/2 = (5+3y)/2
x =(5+3y)/2................................ equation 3
put x = (5+3y)/2 in equation 1
5x + 4y = -22
.................... equation 1
5(5+3y)/2 + 4y = -22
(25 + 15y)/2 + 4y = -22
multiply through by 2
25 + 15y + 8y = -44
25 + 23y = -44
collect the like terms
23y = -44 - 25
23y = -69
divide both sides by 23
23y/23 = -69/23
y = 3
put the value of y= 3 into equation 3
x =(5+3y)/2................................ equation 3
x = (5+3(3)]/2
x = 5+9/2
x =14/2
x =7
Hello, and thank you for posting your question here on brainly.
This fraction needs to be simplified to be able to figure it out.
The greatest common divisible is 2.
Divide the numerator and denominator by 2.
6/4 = 3/2
Now, do the division.
3/2 = 1.5
1.5 is rational.
Hope this helps! ☺♥
Answer: +3
Step-by-step explanation: The answer is positive 3 because if you look on a number line, you will only move 3 spaces to the right. You could also look as this problem as a subtraction problem. 5-2=3. Tip: While adding positive and negative numbers, look at the bigger number in the problem. In this case it's 5. The five is positive so the answer is positive. If the five were to be negative, the answer would be negative. In adding the larger number dictates whether the sum will be positive or negative.
Answer:
1344/19 =x or 70 14/19
Step-by-step explanation:
y=19x - 1,344
to find the x intercept set y = 0 and solve for x
0 = 19x - 1344
ad 1344 to each side
1344 = 19x-1344+1344
1344= 19x
divide by 19
1344/19 = 19x/19
1344/19 =x
