Answer:
Step-by-step explanation: largest=2x+4
their sum =2x+2x+4=36
4x=36-4=32
x=32/4=8
so the numbers are 2*8,2*8+2,2*8+4
that is 16,18,20
Answer:
x = -2 and y = 0
Explanation:
You just put the value of one variable in terms of the other in one of the two equations. Then, solve it and BOOM you'll have your solution.
x + y = -2 ........... (a)
y = x + 2 ............ (b)
Put (b) in (a),
x + (x + 2) = -2
2x = -4 => x = -2
Put x = -2 in (b),
y = x + 2 = -2+2 = 0
Thus, x=-2 and y=0
Answer:
B, -4
Step-by step explanation
Step 1: Simplify both sides of the equation.
3(2x+8)=0
(3)(2x)+(3)(8)=0(Distribute)
6x+24=0
Step 2: Subtract 24 from both sides.
6x+24−24=0−24
6x=−24
Step 3: Divide both sides by 6.
6x/6= -24/6
Answer: x= -4
