I remember doing this problem let me check my corrected hw
Thus, the value of x = 2
Let us check whether or not we have found out the correct value of x, by placing 2 in the place of x :
Since the Left Hand Side and the Right Hand Side of the equation are equivalent, we can conclude that we have found out the correct value of x.
▪︎Therefore, the value of <u>x = 2</u>
That's a triangle with angles 57 degrees and 95 degrees and we're asked for the third angle x.
The sum of a triangle angles is 180 degrees.
x + 57 + 95 = 180
x = 180 - 152 = 28
Check: 28 + 95 + 57 = 180 good
Answer: 28 degrees
-3x+13=16
Move +13 to the other side. Sign changes from +13 to -13.
-3x+13-13=16-13
-3x=16-13
-3x=3
Divide by -3 for both sides.
-3/-3x=3/-3
Cross out -3 and -3, divide by -3, then becomes 1*1*x=x
x=-1
Answer: x=-1
