Solve equation using substitution method 4(x-1)-3x=2

NikAS [45]

Answer:

x = 6

Step-by-step explanation:

Step 1: Write equation

4(x - 1) - 3x = 2

Step 2: Solve for x

Distribute 4: 4x - 4 - 3x = 2
Combine like terms: x - 4 = 2
Add 4 to both sides: x = 6

Step 3: Check

Plug in x to verify it's a solution.

4(6 - 1) - 3(6) = 2

4(5) - 18 = 2

20 - 18 = 2

2 = 2

Please help!! Find BD

Temka [501]

Answer: $8\sqrt{2}$

==========================================================

Work Shown:

Focus entirely on triangle ABD (or on triangle BCD; both are identical)

The two legs of this triangle are AB = 8 and AD = 8. The hypotenuse is unknown, so we'll say BD = x.

Apply the pythagorean theorem.

$a^2 + b^2 = c^2\\\\c = \sqrt{a^2 + b^2}\\\\x = \sqrt{8^2 + 8^2}\\\\x = \sqrt{2*8^2}\\\\x = \sqrt{8^2*2}\\\\x = \sqrt{8^2}*\sqrt{2}\\\\x = 8\sqrt{2}\\\\$

So that's why the diagonal BD is exactly $8\sqrt{2}\\\\$ units long

Side note: $8\sqrt{2} \approx 11.3137$
