Answer:
The value of 5x+2y-6 is 20
Step-by-step explanation:
The problem is substitution into equation.
x and y are called unknown variables
Since we have been given values of x and y, we replace them with the values given to solve the expression.
5x means 5 times x
2y means 2 times y
Step 1. Substitute the given values of x and y
When x = 4 and y = 3
5x+2y-6 = 5(4) + 2(3) - 6 = 20 + 6 - 6
= 26 - 6 = 20
Answer:
<em>Given </em> <em>x </em> <em>=</em> <em> </em> <em>4</em> <em> </em> <em>and </em> <em>y </em> <em>=</em> <em> </em> <em>3</em>
Step-by-step explanation:
5x +2y -6 = <em>5</em><em>*</em><em>4</em><em> </em><em>+</em><em> </em><em>2</em><em>*</em><em>3</em><em> </em><em>-</em><em>6</em>
<em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em>=</em><em> </em><em>2</em><em>0</em><em> </em><em>+</em><em> </em><em>6</em><em> </em><em>-</em><em> </em><em>6</em>
<em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em>=</em><em> </em><em>2</em><em>0</em>

Step 1: Keep the denominator the same. Step 2: Add or subtract the numerators. Step 3: If the answer is an improper form, reduce the fraction into a mixed number. ... Step 1: Find the Lowest Common Multiple (LCM) between the denominators. 7/4 5/6 7+5= 7/5 1 2/5
24+32-3=53 24+32=56 56-36=20
Remember that (a-b)(a+b)=a²-b² and (imaginary number)²=real so if we have a+bi, then a-bi is the conguate because (a+bi)(a-bi)=a²+b² if the complex number is a+bi the conjucate is a-bi
