Distribute-3 to 10x and 4y
Then distribute 6 to 6x and -2y
Step 2: 6x-24y
After that add up like terms
Answer:
x=k/4+c/4
Step-by-step explanation:
4x-c=k
4x=k+c
x=k/4+c/4
The answer for number 4 is 13 and number 6 is 121 and the last problem for number 7 is 112
Answer:
x = 15
Step-by-step explanation:
angles 2 and 4 are supplementary so they add up to 180
2x + 10 + 4x + 80 = 180
6x + 90 = 180
6x = 90
x = 15
