Answer:
Step-by-step explanation:
2 triangle+square=23
square=60/triangle
2 triangle+60/triangle=23
2 triangle^2+60=23 triangle
2 triangle^2-23 triangle+60=0
solving quadratic equation we get
triangle=15/2 , 4
15/2 is not possible so triangle=4
square=15
Answer:
x = 59/7, y = -15/7
Step-by-step explanation:
4x= 2y + 38;
2 - 3y=x
We can substitute for x in the first equation since the second equation is solved for x
4(2-3y) = 2y+38
Distribute
8 - 12y = 2y+38
Add 12y to each side
8-12y+12y = 2y+12y+38
8 = 14y+38
Subtract 38 from each side
-30 = 14y
Divide by 14
-30/14 = y
-15/7 = y
Now solve for x
2 - 3y = x
2 - 3*-15/7 = x
2 +45/7 = x
14/7 + 45/7 = x
59/7 =x
