Answer:
x = 120 degrees
Step-by-step explanation:
50 + 70 = 120
68 minus 19 is 49
So the answer is there are 49 more children in the school then on the playground.
Step-by-step explanation:
x + y = 3 ---------------- eqn 1
y = -6x + 3 ------------- eqn 2
Substitute y for -6x + 3 in equation 1
x + -6x + 3 = 3
x - 6x + 3 = 3
-5x + 3 = 3
Collect like terms
-5x = 3 - 3
-5x = 0
Divide both sides by -5
x = 0
