Y=x+1
y+x=5
cant figure out what i am suppose to do with this problem

can you give me more detail

Step-by-step explanation:

x=2, y=3

Step-by-step explanation:

y+x=5, subtract x from both sides you get, y=-x+5

since y also equals x+1, you can tell x+1=-x+5,

add x to both sides you get, 2x+1=5

subtract 1 from both sides you get, 2x=4

divide both sides by 2 and you get, x=2.

Now sub in 2 for x in any of the equations to get y.

y=x+1. y=(2)+1, y=3.

step-by-step explanation:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
