Answer:
x = -3
Step-by-step explanation:
-5(x+1) = 10
Distribute
-5x - 5 = 10
get rid of the -5 by making it positive and adding it to the other side
-5x = 15
divide 15 by -5
x = -3
Process of elimination and distributive property
To solve, set the equations equal to each other, so 4(2t-1)=2(3t+1). Next, distribute your 4 and 2, getting 8t-4=6t+2. Now, solve for t. 8t-4=6t+2, subtract 6t from both sides, 2t-4=2, add 4 to both sides, 2t=6, and divide 2, t=3. Now that you have your value of t, plug it into either equation, 4(2(3)-1)=4(6-1)=4(5)=20. This means they each picked 20 apples.
For this it is two variables. In total it is the amount of adults plus the kids but don’t know how much for each one. Hope this helps
