Answer:
31√3
Step-by-step explanation:
48√3 + 45/√3 since the base is same we can add the terms up 93√3
➡ 93/√3 × √3/√3 = 93√3/3 ➡ 31√3
Solve for x in first equation:
x-2y=7
Add “2y” to both sides
x=2y+7
Put this in to second equation:
3(2y+7)+2y=21
Solve for y:
Distribute the 3 into the ()
6y+21+2y=21
Combine the like y terms
8y+21=21
Subtract 21 from both sides
8y=0
Divide by 8 on both sides
y=0
Put this into the first solved equation:
x=2(0)+7
Solve for x:
Multiple 2(0)
x=0+7
Add 0 and 7
x=7
So the value of x is positive 7.
5(x+4)=-15
Distribute
5x+20=-15
Subtract 20 from both sides
5x=-35
Divide both sides by 5
x=-7
Final answer: The number is -7
