Answer:
1. x+5x= 24
6x= 24
x = 4
2. x+y=12 y=-x+12
3x + (-x+12)=8
3x-x+12=8
2x=8-12
2x=-4
x= -2
Step-by-step explanation:
ang sa pic po yung sagot sa isa mong question
graphing paper lng po yong gamitin mo :)
GRAPH THE FOLLOWING SYSTEM OF EQUATIONS
1.x-y=5 and 2x - 2y = 10
2. 2x + y = 5 and 3x - y = 9
3. 2x + y = -6 and 2x + y = 10
1.y=5x and x+y=24
2.m=3n-4 and m+n=12
3.a+b=12 and 3a+b=8
4.3x-4y=0 and 2x+y=33
