The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try!
Stop if u not going to ask a real question dont
8x+4 = 6x-10
To solve for x you'll want to move all the terms containing x onto the left side of the equation and all the other terms on the right side of the equation.
1. Subtract 6x from both sides.
2x+4 = -10
2. Subtract 4 from both sides.
2x = -14
3. Divide both sides by 2.
x = -7
Answer is:
-7
since ΔCDW similar to ΔUVW, then
UW/CW = UV/CD
UW = CW•UV/CD
CU+CW = CW•UV/CD
CU = CW•UV/CD - CW
= 26•132/24 - 26
= 143 - 26
= 117
She is 24
24+2=26
26(1/2)=13
13+((24-3)1/3)
13+(21*1/3)
13+7=20
Therefore she is 24
