Answer:
x = 4
y = 1
Step-by-step explanation:
use one equation to solve for one variable.
y = 5 - x
Now plug the value of y in the other equation
x - (5-x) = 3
x+x= 3+5
2x=8
x=4
Now use the value of x to find the value of y on the first equation
y = 5 - x
y = 5 - 4
y = 1
Answer:
E': (-3, 3)
F': (-1, 2)
G': (0,0)
H': (-2, 1)
Step-by-step explanation:
Answer:
x= -1
Step-by-step explanation:
First add 2x to the 7x it will look like this
9=9x
Now you need x by itself so divide 9 on both sides it will look like this
1=x and thats your answer just swap the x and the 1
Answer: All but one was right
1. 0 (correct)
2. 34 (correct)
3. 398 (correct)
4. -350 (correct)
5. 20 (correct)
6. 200 (wrong)
7. 48 (correct)
8. -1000(correct)
9. 150 (correct)
10. -55 (correct)
Step-by-step explanation:
(2x5)x(9÷3)+4=10x3+4=30+4=34
4(25x8÷2)+3-5=4(200÷2)+3-5=4x100+3-5=400+3-5=403-5=398
-10x20-30(5)=-200-150=-350
5x10-30=50-30=20
4(50-20÷4)+20=4(50-5)+20=4x45+20=180+20=200
3x4(20÷5)=12x4=48
-20(50x2)+5(200)=-20x100+5x200= -2000+1000=-1000
20x5+70-20=100+70-20=170-20=150
-5+10x(-5)==5+-50=-55
