Answer:x=−24/11
Step-by-step explanation:
Simplifies to:
x−86x=79
Let's solve your equation step-by-step.
x−86x=79
Step 1: Cross-multiply.
x−86x=79
(x−8)*(9)=7*6x
9x−72=42x
Step 2: Subtract 42x from both sides.
9x−72−42x=42x−42x
−33x−72=0
Step 3: Add 72 to both sides.
−33x−72+72=0+72
−33x=72
Step 4: Divide both sides by -33.
−33x−33=72−33
x=−2411
Answer:
x = 1.5 ; y = -0.5
Step-by-step explanation:
2x + 4y = 1 ---------------------(i)
3x - 5y =7 ----------------------(ii)
(i) * 5 10x + 20y = 5
(ii)*4 <u> 12x -20y = 28 </u>
add, 22x = 33 { here y will be eliminated}
x = 33/22 = 3/2
x = 1.5
Put the value of x in equation (i)
2*1.5 + 4y = 1
3 + 4y = 1
4y = 1-3
4y = -2
y = -2/4 = -1/2
y = -0.5
The solution to the inequality x-13<=7+4x is x >= -20/3
<h3>How to solve the inequality?</h3>
The inequality expression is given as:
x-13<=7+4x
Add 13 to both sides of the inequality
x <= 20 + 4x
Subtract 4x from both sides of the inequality
-3x <= 20
Divide both sides of the inequality by -3
x >= -20/3
Hence, the solution to the inequality x-13<=7+4x is x >= -20/3
