How many solutions are there to the equation 4(x-5)=3x+7
stich3 [128]

Answer:

x=27

Step-by-step explanation:

Let's solve your equation step-by-step.

4(x−5)=3x+7

Step 1: Simplify both sides of the equation.

4(x−5)=3x+7

(4)(x)+(4)(−5)=3x+7(Distribute)

4x+−20=3x+7

4x−20=3x+7

Step 2: Subtract 3x from both sides.

4x−20−3x=3x+7−3x

x−20=7

Step 3: Add 20 to both sides.

x−20+20=7+20

x=27

Answer:

x=27

Please help find the value of x and show me steps so I can try to learn it!!
fiasKO [112]

Answer:

x = 30

Step-by-step explanation:

If we take a look at the given picture, we can see that both sides are almost completely identical, so they must almost have the same value.

Let us do the plug in. Keep in mind that the angle is obtuse, meaning over 90 degrees, and angle identical or lower than 90 is incorrect.

x=18

(x + 90)°

(18 + 90) = 108

True.

4x

4(18) = 72

False. Meaning the 18 would not work.

x = 22.5

(22.5 + 90) = 112.5

True.

4(22.5) = 90

False. Meaning that 22.5 does not work.

x = 30

(30+90) = 120

True.

4(30) = 120

True. Meaning that 30 is the answer and can work.

x = 54

(54+90) = 144

True.

4(54) = 216

False. Although the angle is larger than 90, 180 is a straight line, and we can see that the angles given are not straight lines or greater.
