Step 1: subtract x from -3. New equation should be y=-3-x.
Step 2: plug that equation into top equation. Should be 5x + 2(-3-x) = 9.
Step 3: use distribitive properties on 2(-3-x). New equation is 5x - 6 - 2x = 9.
Step 4: combine like terms. New equation 3x - 6 = 9.
Step 5: work it out. Divide 3x and 9 by 3. New equation is x - 6 = 3. Add 6 to -6 and 9. Final eqaution is x = 9.
Step 6: swap 9 for x in second equation. New equation is 9 + y = -3
Step 7: subtract 9 from 9 and -3. New equation is y = -12

Step-by-step explanation:
To find 20% of $150, we do:
0.2*150=30
So, 15% of $150 is $30.
Answer: 4/7
Step-by-step explanation:
The probability of would be 4/7. In total there are 7 bowls of ice cream in total so that will be the denominator. 4 of them are chocolate so it'll be the numerator.
