Solve the equation 15x+2=45x+4

Mathematics
1 answer:
BaLLatris [955]3 years ago
5 0
15x + 2 = 45x + 4

Subtract 2 from both sides, as well as subtracting 45x from both sides.

15x - 45x = 4 - 2

-30x = 2

Divide both sides by -30.

x = 2/-30

x = - 1/15

Llana [10]

Answer:

Step-by-step explanation:

x−log(48)+3(log(2))=

1

3

(log(125))−log(3)

Simplifies to:

x−0.778151=0.221849

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

x−0.778151=0.221849

Step 1: Add 0.778151 to both sides.

x−0.778151+0.778151=0.221849+0.778151

x=1

Answer:

x=1

Use substitution to solve for x in the system of equations.
jolli1 [7]
Equation 1) 10x + 2y = 30
Equation 2) 4x + y = 4

Multiply all of equation 2 by 2.

2)  2(4x + y = 4)

2)  8x + 2y = 8
1)  10x + 2y = 30

Subtract equations from each other.

-2x = -22

Divide both sides by -2.

x = -22/-2

x = 11

B) x = 11

The sum of two numbers is 44. The sum of the smaller and 6 times the larger is 159. Find the numbers.
nexus9112 [7]
X + y = 44 (multiply by negative 1)
x + 6y = 159

-x - y = - 44
x + 6y = 159

5y = 145
y = 29

X + 29 = 44
x = 44 - 29
x = 15

<span>X = 15 and y = 29</span>
