Answer:
-7
Step-by-step explanation:
x+3y
Let x =2 and y = -3
2 +3(-3)
2 -9
-7
Answer:
x = 34
Step-by-step explanation:
F = 180 - (90 + 42)
F = 48
2x + 64 + 48 = 180
2x = 180 - 64 - 48
2x = 68
x = 68/2
x = 34
The equation -21t - 4 = 10 - 2t has only one solution
<u>Solution:</u>
Given, equation is – 21t – 4 = 10 – 2t
We have to find how many solutions does the above given equation have
Now, let us solve the given equation to find the number of solutions it has.
Then, - 21t – 4 = 10 – 2t
Taking like terms to one side of the equation we get,
- 21t + 2t = 10 + 4

here we can see only one value of t.
Hence, the given equation has only one solution.
