Answer:
x = 10
y = 25
Step-by-step explanation:
if you add the equations as they are then the 'y-term' is eliminated:
60x = 600
x = 10
substitute x=10 to find value of 'y':
40(10) + 4y = 500
400 + 4y = 500
4y = 100
y = 25
Check:
20(10) - 4(25) should equal 100
200 - 100 = 100
100 = 100
1+1+1+1×1×1+1+1+1+1+1+1+1+×1×1×1+1+1+1 = 14

Answer:
11
Step-by-step explanation:
1+red/3=4/1 so 1+red=12 so red=11. we should add 11 red counters
-5(x+7)<-10
ok so we need to distribute the -5 into the x and 7.
-5x+-35<-10
then, we combine like terms.
-5x+-35<-10
+35 +35
-5x<25
Then, we get the variable to be by itself.
-5x<25
divide by -5
x<-5
Hope this helps! If you still don't get it, ask me.
